Yup, no TC for now. But things are pretty good now, so no more new stuff to learn! There is enough and more to do with the coil/wicking stunts :D
That YT link was good, will go through his stuff. The way he patiently explains is pretty nice ! Man, this whole vaping has some superb stuff on YT, a blessing for people like me!

@Letitia
Will try the parallel build the next time for the intake. However today morning, the ammit 25 did have some spitback. There is absolutely no leakage but there is still spit back. Wonder what more I can tweak with the wicking, anyway will give it a shot again tonight to see if there is something I can do even better on the wicking front.
Did buy a geek vape set of 8 fused claptons. Like you said, I think it is time to settle down and give my preferences a priority. Surprisingly enough, just like you said, I am enjoying the 1.23 ohms resistance on the intake more today. It is a cooler vape and I am ok with the vapour and flavour. I think the spit back is preventing me from enjoying the mojito on the ammit but there is no denying that the ammit has better flavour and vapour. Now is that a tank thingie or is it the twisted coil thingie I do not know. Will experiment more with the ammit, maybe a single wire build on it the next time would help me nail down what I want. If only that damn spit back does not happen. I dont suppose spit back could be due to watts right? I do slow but long drags just to make sure that my inhalation does not cause spit back. More to experience and refine I guess :)

@stols001
Thanks for the kind words !
Honestly it has been a pleasure hanging out here to learn things. There is an automatic inspiration that you guys manage to instill, so it is no surprise at all that I am getting a hang of things this fast. And it has been great fun. Thought the trial and error would be frustrating but the journey in of itself is proving to be quite some fun. Not to mention burnt tongues :D

Spit back is caused by so many factors, this is why it is important to only adjust one thing at a time. Tedious but necessary imo, took me umpteen wicks over 2w to find my sweet spot with the Nano. You'll get better flavor from the Intake if you raise the coil a touch more than the reviews are showing.
20180802_173520-1.jpg this coil is warped because it was installed to be closer to af. Pulling it up improved flavor quite a bit for me and others. I'll be changing out the coil soon, I'll post a pic of the fresh build for you.

Spitback can also be caused by too high or low wattage setting, as well as coil and wick placement as @Letitia says, coil placement can make a large difference so keep experimenting.

I think you learned a lot so fast, because you asked a TON of relevant questions, honestly. But I'm glad its going well!

TC takes most new vapers a few months to get into, if they're in a hurry, so yes, no need to rush (there are plenty of vapers who don't use it at all).

OK, more confusion! I just used the ammit for its remaining 2 ml or so for the past hour or so. No spitback at all!! So I am not sure what is going on here. And I kept it at the same wattage as last night !
So what are the factors that I should look for here? I am going to rewick the ammit again, just to get some more practice ! So other than cotton, coil placement and watts what are the factors that I should bear in mind?
I wonder why the wicking degrade from yesterday ! Anyway more experimenting - here I come :D

Please do post that pic, would be enormously helpful :)
My intake is doing just fine with the 1.23 ohms, maybe I am meant to do plus ohm vaping :D

@stols001
Yeah, I am steering clear of TC for now. Its all kanthal A1 for me now, so anyway I am out of TC range!
Like Letitia said, I will try and change one variable keeping all else constant to get a better hang of this. Surprisingly the Intake has presented no issues at all. I see tons of people complaining about the ammit 25 leaking issue! So I take some comfort in that :D
I somehow feel that the 0.63 ohm twisted coil is pretty good. I think the ammit performance is purely due to wicking. Next time maybe I will do a single wire coil on the ammit to see how that goes!

After having spent a lot of time watching videos and getting a lot of answers to my questions, I have a fairly decent picture of some of the science that goes into vaping. However there are some aspects that still beat me, I just wanted to enumerate them over here so that I can get an even clearer picture, so kindly bear with me for some more questions :)

1. I understand that resistance plays very little role in the regulated mods as everything is dictated by us as to how much power is being delivered via the wattage setting. I also understand that the crucial factors for clouds and flavour is in the surface area of the coil (hence more coil in contact with the wick) and the quality of the vaporisation rendered by the coil (more so the wire used within!). As a result it makes sense that fused claptons and all those fancy coils given their increased contact area and the quality of the wire (is this true!?) result in enhanced flavour and vapour. Now using simple kanthal A1, is not correct to deduce that I can increase the contact area by just giving out more wraps. Yes, that does increase resistance but I can always increase the watts. So theoretically, using simple round kanthal, by increasing the surface area of the coil I should be able to get the increased flavour and vapour (maybe not as much as the fancy coils but certainly comparable). But if this were the case then my 1.23 ohms on the Intake, if fired at higher watts should do well but consistently when I power that atty at 50W I get a burnt taste. This probably means that the coil is not able to keep up with the power delivered correct. So what gives?

2. I have a similar reverse question with the 0.63 ohms twisted coil. Should this again not provide advanced flavour given the increased surface area (and the fact that it is actually sub ohm resistance).

3. I think what I am trying to wrap my head around is this - how do I get more flavour and vapour in a regulated mod given that resistance plays an insignificant role. In a high resistance more wraps coil, more wattages should get the job done. As for how to build a low resistance wire, I am not even sure how to do that yet? The twisted did give me a sub ohm resitance but does that mean that a simple single wire A1 kanthal can not deliver sub ohm resistances? I assume that when the resistance is low, lower watts are enough to perform the vaporisation and give out the cloud and flavour, so at slightly increased wattages massive clouds and flavour can be obtained!

From my limited understanding, it is all in the coil wire and material. Maybe kanthal is just for starters and does not really support lots of flavour and clouds. Maybe only those fancy coils can (I guess they do have nichrome too right?) - so maybe the quality of the vaporisation is much better there which lends to massive clouds!

These are just more hobbyist questions, I am not switching out to become a flavour or cloud chaser (though I want to !!) Like you people have advised I am still going to experiment with what I have at hand right now. Just wanted to understand how to get those massive clouds and vapour given that I have good mods. Maybe single coil RTAs are not even the right attys for that. I can understand if that is the case.

Apologies for the continued interrogation, just feel like a kid with so much to learn and this seems to be the best place to do that :)

K, I personally believe coil surface area is a bit over-rated. Fancy Claptons, Aliens, and other exotic coil builds often adds more mass; more mass means more metal to heat up; which means it can take additional time (ramp up time) to get the coils hot enough to produce a satisfactory vape, plus it takes more energy to get to that point (additional drain on batteries). In other words, you can quickly reach a point of diminishing returns when it comes to surface area.

We're starting to get into territory where I'm not that comfortable in understanding or explaining. Coil experts tell me the most important factor in coil building is "heat flux". You'll have to look that one up for yourself. We're getting above my pay grade. :unsure:

This is why I stick to my KISS principle. Keep It Simple, Stupid. ;)

Experimenting! Yeah given that it works now, it does not make sense. But I have run out of that juice anyway and I thought I can play around with the wicking again. I guess I was wondering why I was getting that spit back. Also wanted to see if I can repeat my moderate success :)
I would guess a bit of caramelized juice gave you your wick even contact with the coil. The entire interior of the coil needs to be in contact with the wick. I still think your wick isn't as tight as it seems to you.

That is a very distinct possibility. I did knock out the outer layers of the cotton as some videos suggested, so it could have rendered my cotton pretty thin. Another reason to rewick :)
I always remove the outer skins from KGD pads. I normally use the Scottish roll as well. Easier for you to watch on yt than me explain it. I don't pull the pad out as thin as they do, about half as much. Works very well for me.

Hmmm... I am still using the coil master cotton, yet to graduate to the cotton bacon that I have. I did watch some Scottish roll videos, yet to actually use them. Need to get some more cotton to kind of experiment there. Will use that for today's wicking !! The ammit, looks like from my previous experience, requires a lot of cotton yet not too densely packed into the bottom, that is what I have kind of discerned. Scottish could fit the bill quite well, just need to ensure that the ends are really fluffy (that was another thing I did last time) and that I dont pack it in too thick.
One question - assuming I want to produce massive clouds with my current set up of mods and attys, the only way is to get to SS wires right?

No, you can get clouds with kanthal and Ni80 too. Clouds are dependent on build and vg ratio. High vg = clouds. If you want dense fluffy white clouds max vg is what you'll need. Bigger id coil and af wide open helps. Try a 3.5mm coil .3-.5 resistance.

See now thats the problem. If I enter single coil, kanthal A1, id of 3.5 and a target resistance of .3 I get 2 wraps (3 wraps for .5). All my juices are 70/30, so I am ok on that front. But a 2 or 3 wraps coil is seemingly impossible. Maybe 24g, that gives 5 wraps! Invest in some 316L 24g??

Apologies Anathan, I've been using ss long my brain just goes there.:facepalm: 5 wrap 3.5 mm ss 316l is 4.6Ω. With kanthal you will need a 4 wrap 3.5mm parallel for .33Ω or 5 wrap for .41Ω.

Gotcha !
On the flip side, just get some 22g and 24g kanthal and be done with getting sub ohm res with no parallel or twisted shenanigans :D
Remember thicker wire = longer ramp. Might want to set the ramp on high in your mod settings. I personally don't care for wire larger than 26g. You should try Ni80 wire, think you would like it.

I recently put a couple builds of exotic wire in two of my mods and one it's working out pretty well on, another I really do need to vape for awhile to get flavor. It's annoying, and I'm considering removing it for a single round build. IDK why one is needing more ramp up than the other but I'm not really LOVING the outcome, and I might replace it today. It's annoying to have to take 5 vapes before I get any vapor, and it's a fairly high ohm's coil.

No clue why one is working out better than the other, but I'm not too stressed about it, I will probably just replace it, at least in that build. That can be the issue with more massy builds, I do run into these issues from time to time and usually I just wind up going back to my nice simple round wire build, etc.
