Remember the learning curve is there, many subpar wicks will still work, but will gunk more than normal because they are not proper. As you get more experienced it only gets better then you hit that sweetspot and bam.

Are you saying break-in was long. Typically that would mean too tight. The amount of time it took to "break-in" should relate to how many strands too many you had in the coil. To ensure that you have enough wick I like to see a few breakin hits like 5-6. I usually blow them out the air holes. better varieties have a cleaner taste and thus less on initial use. I have no control over the Sally's consistency, its the cheapest rayon, so it's not as good as others, op post 5. But a rinse to Sally's will make it much better on break in taste, other forms of rayon receive more rinsing. If you do you Just have to try to keep it in strips so when it dries it still resembles itself.

On the TC, yeah it could work. But kanthal is excellent for me too. I've decided some of the issues I have with TC is the atomizer FEV. Not great for TC. It's a wired base and the wires are throwing it off. I rarely ever drip I don't have any need to. I'll be getting a couple new single coil atties soon that will TC well. Im a single coil guy. Duals, bah too much trouble. No benefit for me really, I seem to get plenty of vapor for my needs. 35- 45 w single spaced coil 28-26g is where I've been in the FEV for a long time.. High heat Flux and low capacity.

I definitely see the learning curve. Got so used to the KGD cotton, will have to learn the ways of the rayon master! Gonna play with different wick consistency and wire configurations till it is fine tuned.

As for the rayon, went with the Kotex U. Was able to try it first without the huge Sally's box commitment. Also figured it would be of higher grade, given its intended use. Dissecting the first one was interesting...getting the string out without mangling the whole thing proved challenging. Ended up performing surgery on it with an x-acto knife to get a useable piece. Will consider those delasco balls.

I'd like to pick your brain a bit good sir!

Firstly, I've been using close wrapped 3mm 24ga ss316l coils. Is there a difference between ss and ti in regards to flavor and vapor? Spaced vs close wrapped?

To be honest, my experience with the other wires is about 2 days. Only received my spools of Ti and SS on Monday. Until then, had just been a Kanthal guy, with a few nickel builds here and there. Not super impressed with nickel, it sucks. My first SS coil was claptoned with Kanthal so that would skew the results taste wise. Vaped today with the spaced, single strand Ti coil. Tomorrow, going to give a spaced SS coil a go. Yesterday, had to communicate with Vaporflask about how to get this thing to adjust wattage in Temp mode, so just threw a Kanthal/Cotton build in until it was sorted. Will keep you updated with my thoughts on wire difference. So far the Ti wire seems to offer better performance in ramp up and cool down. Hope SS does as well or better. I like the idea of being able to use it in either TC or conventional VW mode.

As far as spaced vs contact, seems spaced works better for this setup. I have changed a few things all at once so we'll see. Spaced coils dissipate heat much better. Contact coils (with Kanthal) always gave me much better flavor on cotton, but gunk much faster. With rayon's superior wicking, suppose this doesn't matter anymore. After I try a few different setups, will share my thoughts.

Yes and yes. Spaced coils are better with any wire.


I finally got the wicking technique down right and I had to take it out. It was too sweet for me, I am so used to cotton that the rayon was actually overpowering. Thanks again for your advice everybody!

You really have to turn it up from cotton at least 5w if not 10 to see how it performs. It takes more power than cotton other wise you have too much saturation and that makes it rich like a flooded hit. The whole point of rayon from the start, is that your build and atty will be able to reach higher wattage than you could achieve with cotton. Because rayon can keep up with higher temperatures. As long as its touching the coil, or your loose wrap could overheat.

The original recommendation I made to new users was a mandatory 3-5w bump in power to start with; compared to what they were with cotton yesterday.

Great to hear. I would do the Griffin tail setup like I did here - Rayon wick, b.... CLT Rayon
I'll try thanks! Problem so far has been thinning the tails too much makes it leak, but not enough and I get dry hits. this is with both longer and super short tails

This is how I wicked mine:



It doesn't show well, but I reduced the tails 75% or so and taper the ends to follow the curvature of the tank. Leave just enought to peek just below the wick ring, and this thing vapes like a beast!

I prefer spaced coils with any wire, the more I can space them out, the better.
SS vs Ti.. vapor wise, no difference.
Flavor - actually taste from the wire - is a close call between the two, with a slight preference for Ti, I find it more neutral.
As a matter of fact I use SS316L on all my unregulated devices, mainly mechs, and Ti for TC mods.
All of them rigorously wicked with rayon, of course ;)

Looks real good from here on the river.. coil stats and wattage please, inquiring minds..

So looking closer at this Griffin now... I've been looking as I'm finally going to get two new atties... I'd say 7-8 wraps of that wire would probably be ideal for it considering the amount of room in there and the deck.. With a non-contact spaced the whole coil will heat evenly, not primarily the center coils. So it can affect the way you build.

Still currently running this build/wick. Loosened up the wick a bit, as you suggested. Greatly improved the break in time. It is a 3 mm, 10 wrap 316L SS, coming it @ .27 ohm (dual coil). Vaping quite nicely at 50 watt 450f. Not sure of my temp coefficient is correct. Been playing with it a bit.

Wouldn't the tcr values for ss316l already be defaulted in ss mode?

After almost 2 years of vaping I find myself interested in Rayon. Quick question and I apologize for not having read the whole thread (I intend to, a few pages each morning) - where can I get some other than Sallys? I'd like to try the better stuff, and not have to deal with rinsing or cleaning it beforehand. From what I've read, seems like Sallys needs rinsed.

Sitting down, facing forward.
I'll second what Paul said. I started with Sally's, Graham CelluCotton, and have never rinsed or done anything to it prior to using it for a wick, other than separating what I need and "massaging" it into a uniform shape. Some folks may have more sensitive taste buds, though, and as a result may taste things I can't.
