I got my order from byLeo yesterday. As you can see, I don't do anything half-hearted. Two is one, one is none, and if it's a bit esoteric, spare parts are a must as far as I'm concerned: :D

I was really excited. I've basically given up on cartos, but really like my IBT tanks, and I figured this would be their salvation. Well, not so fast. First, I re-discovered why I don't like cartos that don't have flanges; you push your tank down a little too far and it leaks. Second, you may not need Leo's red silicon o-ring in a 35mm (standard length) tank where you can adjust the juice control by grabbing the upper part of the the Sophia's body, but if you want to use a 45mm (XL) tank, the only thing that will turn the juice control is you drip tip and the low-friction o-ring really helps.

OK, so how does it vape? I can see the potential here, but honestly the stock coils with silica wicks are (IMO) awful. Once you get used to cotton, it's really tough to go back to silica, and I've gotten used to cotton in my Squape and even in my Kanger tanks. Moreover, the coils that came pre-installed don't wick well at all and taste quite dry. Obviously, I'm going to need to make my own coils and wick 'em with cotton if I'm going to be happy with these, but... I neglected to get any NR wire. Which leads me to a question:

Is the whole NR-R-NR nonsense really necessary, particularly with a micro-coil? Has anyone tried just using straight Kanthal?

I realize this is going to put some heat into the ceramic, but it's ceramic and should be highly heat resistant. It seems to me that the only part that might be problematical is the blue insulator, but I don't think the wire touches that, does it?

Thanks for the "thoughts on not using NR wire" link. At 440 pages, that thread was a bit daunting.

Any thoughts on which of Stormy's wires are most suitable for a micro-coil and cotton setup? What his page lacks is a description of those wires (i.e. the length and gauge of the resistance section). I'm running a regulated mod (DNA 20).

OK, 1.5, 1.8 and 2.2 ordered. But I'm not sure I'll be able to keep myself from building one with just plain Kanthal this weekend. :laugh:

There is a way but the biggest issues will be heating the tube and melting rubber pieces. Since NR doesn't transfer heat and R does anything contacting the R wire gets blasted. So you have to alter the setup a bit. Because the tube is steel it will continue to transfer that heat. There's no way to

Bad things happen will happen with extended use of a straight R wire setup.

Stormys ready made wire does not really suit micro coils because the kanthal in the middle is just too short. I tried it, didn't get any better flavor. My best flavor seems to be a 5\46 drill bit with 5 wraps. Now if you make your own nr-r-nr wire, you can drop your ohms and get many more wraps of the kanthal. Since I don't require more heat, and don't have a wire joiner, and don't want to show off my horrible knot skills, I just stick with the stormys for now.

Hmm... I use stormy's 2.4 Ohm ready wires. Maybe making a micro works for me because it's a bit longer?

on a 1/16" I make one NR wrap, on each end, and 7 R wraps for a total of 9 wraps and it seems to work well to me.

It course, if it works BETTER to use 30ga with a zapper so I can get more coils then I really should get myself a zapper stat!

Works fine for me. Works well all the way to 2.2Ω I'm probably doing it wrong...

maybe there are helping heads with ideas for my Sophia (in Salt'n'Pepper Tank)

I use two of these - one with 22mm Salt'n'Pepper and long body Sophia - works fine, never ever got a problem.

The second one is a 23mm Salt'n'Pepper and standard Sophia (I use only readymade LR coils by Leo, not wanting to do these by myself). This is giving me problems: the Sophia is open one turn and works perfect - suddenly (after few inhales) it gets weak vape, starts to gurgle (and sometimes I get the juice in my mouth when pulling), so I close the Sophia, but it's too late after 2 inhales when gurgling. I screw the SnP and Sophia off, and the Bottom is wet all over (did heavy wetting all over in my pocket once). I clean everything dry - and it's working again. What the ....... is happening here? any ideas? I changed the O-rings in the tank already, worked for a short time by luck, I guess...

When it works, there is not the slightest problem getting liquid to the coil, and the cape is very very good. I also got the feeling, that the other Sophia (the working one) does a little bit of the same when getting low of juice (2mm in the tank), but it's easy to handle (close liquid flow, do few inhales, fine again).

The juices is the same in all my configurations (50/50 PG/VG, readymade), have changed coil...

But I'm not sure on one thing - is the problem to be found in the Sophia, or maybe the tank - any ideas?

The one that's leaking is flooding. One turn may be too much in that tank. The vacuum being created may not fit the 50/50.
When you next clean it out, vape it closed to get the baseline. (How many vapes before taste starts to turn as if it needs juice). Then open Sophia, let the bubbles come up, then close and only crack it about 1/4 tank.

I tried the following - hope I got you right:
vaped (Sophia closed) till it slightly got burned/harsh taste
opened the Sophia (needs 3 full turns to let the bubbles come up)
closed it again
opened it up to about one quarter turn

works for a while, then it starts to taste burned/harsh again

edit/added: opened it a bit more (half turn, I guess) and it's doing fine at the moment - will observe that for a while and will do the drunken vapor test with these tonight :evil:

thank you very much, yankeebobo - you helped a lot - sometimes I cannot see the clear things because of the clouds of vape in front of my weak eyes ;)
