I do believe in "spreading the wealth" of rayon. I just mailed an envelope to England, this morning, to help someone give it a try.

Sorry but Rayon, don't like it. I really hate the dry throat it gives me plus if I get a dry hit it's the nastiest, most disgusting thing ever. I rarely ever get a burnt hits but it happens at times. As for the benefits I constantly hear about Rayon over cotton, my coils will gunk up long before the cotton even comes close to breaking down. As for wicking speed, Koh gen Do is fast, almost as fast as Rayon. Then on the plus side cotton retains the juice much, much better than Rayon. So all in all for my rta's, RDTA's and RTA's it works for me.
Bottom line though is this, keep an open mind and try everything. Use what works for you, it's not a religion

And, it would be a pretty dull world if we all liked the same things!
Yup, use what works best for your stuff. I used to only use Ekowool and silica. I Hated all the cottons. Then one day I tried Rayon and I find it works great. I haven't used my strings since that day.Sorry but Rayon, don't like it. I really hate the dry throat it gives me plus if I get a dry hit it's the nastiest, most disgusting thing ever.

I think I will try strings again... Just to see how it works in today's tanks.

Only other thing I can add is to make an honest effort then make a good evaluation.

Same thing here.. I got the large 44043 since it was only ~$5 more for roughly double the amount - at $20 from Sally's. I'll just make sure never to put it near anything with a fragrance or odor. With cottons, I always get a sock taste.. Not a dirty sock - but a sock nonetheless.
I hadn't touched the over 130 feet of FastTech silica since then --- until about a month or two ago I started doing re-wicking with silica tests.. Just to use it up, in drippers. I somewhat successfully used it in an authentically challenged Kayfun 5 mini (IIRC?) RTA, but it was subpar - using rayon tufts to sort-of plug things up. With tanks, I don't see it working out for the most part. So now I'm starting to use it in RDA's only.
BTW - to rewick with FT's silica, using some looped up wire to pull doubled-over strands through the coil (i.e. threading the needle technique)... I found that coil diameters of 2mm would fit 1 strand doubled-over (so 2 in total), and 3mm diameter would fit 2 strands double over (4 in total). This was'nt effective with nickel-only coils, as it's too soft - but it will work if the nickel is twisted with some harder wire like Kanthal.
But that's only with FT's silica, which I think was "2mm".
I still like Rayon better as it seems to wick much faster/better, but I wanted a way to use my hoarded silica stockpile.
It will be nice for the gunking juices though, since you can dry-burn it verses having to rewick.I'm having trouble understanding this part, though. If you''re referring to the way it holds juice, I think that would be a bad thing in an RDA. In an RDA, cotton does actually retain the old flavor for longer since cotton works more by an osmosis effect, as opposed to a pipe like rayon.. So the old flavor will sort of be 'stuck' in one part of the wick, while other parts of the wick take on the new flavor. To me that's a bad thing when switching flavors in an RDA.
.... The only other thing I can think of here, is that you're referring to your RTA's leaking. To which I would say that the rayon needs to be packed tighter into the coil, as it shrinks rather than expands. You might also be thinning out your tails too much. I've read the part about the so-called need to thin the tails out, but IME I think that part is heavily overrated - just use whater amount is necessary for the tank not to leak.
As far as the dry-hit goes, to me cotton is the same as rayon, to my 'palette' - they're both nasty. But then, as we know, tastes are different to different people.
As far as the dry throat, I think somehwere, someone posted reasons for that. I can't precisely remember them off-hand.. But I think it was because of the fact that there's more vapor being produced and also more nic-hit.. Since the vg and/or pg is drying (I forget which). I think another was since people coming from cotton are used to cotton expanding, they don't pack enough rayon into the coil - leading to some parts of the coil being dry (and therefore, also hotter and dryer). Maybe someone that remembers those more precisely can point them out.
However, the point about coils gunking well before the cotton/rayon breaks down is well taken. I totally find the same thing - unless of course, one accidentally dry hits, even just a tad too much, a tad too often. In that case, I'll find that the rayon can be eaily pulled off each side of the coil, leaving the coil empty. Although I find that a properly packed coil of rayon will be slightly harder to burn than its cotton counterpart.
..... To mitigate the problem of quickly gunking coils is to use spaced coils, along with adding either less or no sweeteners to your juice (if DIY'ing) - nor FW Yellow Cake.

Yes it is! Thou hast commited blasphemy upon the almighty Rayon gods!

Oh I packed it nice and tight in my coils, no problems there. As to cotton soaking up juice better than Rayon, yes it's a good thing.I'm having trouble understanding this part, though.

Dry throat, I just don't like it and contrary to what is said about no flavor I can taste a distinct difference and I don't like it. I used Rayon from Sally's. I gave it a good run for a fair evaluation and I honestly can't stand Rayon.
Coil gunking, on average I get around 5 days on my hot builds or a couple weeks on my Tootie Puffers. Mostly depends on juice also add to the fact that I run fused Claptons.
Anyway like I said everyone should keep an open mind, give things a fair try and just use what works for you. For me, it's Koh gen Do.

Maybe you packed it in a bit too tight, then.. I also think the preached tightness aspect of rayon to be a bit overrated, too. But it does do better when packed in a bit tighter than cotton.
If we're talking about soaking up more juice though, then I notice just the opposite.. Rayon soaks up a ton more liquid IME. And I'm just now experimenting again with Japanese cotton, to get rid of it.. And it's almost ridiculous how much more juice is soaked up by rayon. But for a dripper, it's also important that it lets go of previous flavors quickly, when switching flavors - which rayon does.
But the fact that you run claptons would make a difference as to how much of an improvement there might have been... Claptons act as both a buffer and a wicker - to make up for the slower and uneven wicking of cotton. So there would be less difference than if you were, say, running straight round wire and cotton. For me, rayon was such an improvement that I didn't notice much/any difference in flavor between Clapton-rayon and straight/twisted-rayon - since the rayon wicks as fast as the coil can use it anyways, so there's no need for the Clapton wire 'module' to act as a buffer/wicker.
BUT.. As is always said.. Everyone has very different reactions as far as taste goes - on top of different preferences. Like with cilantro, there is even a gene that makes it taste like 'bad breath' to some people, including me.
Also make sure you were using the right rayon. There is a wrong one that states something like 'outer strengthening layer' - which, IIRC, is a cotton-rayon mix. (EDIT: Furthermore, make sure you know the source.. Enough to know that it was not placed near something with a fragrance or odor. If you smell directly in the box/bag and smell something, then most likely it was. That also might account for the strange taste you experience.)
... Just want to make sure you correctly experimented with the correct rayon.
If you did, then maybe you can donate it to somebody.. Just not me, as I most likely already have a lifetime supply.

Cotton for me always has a ton of juice left over in the tails when vaping a coil dry. I can vape Rayon bone dry, which is great for changing flavors.
At what temp does rayon burn?
I'm trying to get my Billet Box s/u for tc using the Racing Bridge with the KangerTech Subtank Mini RBA Plus Coil Head. I apparently don't have it wicking right yet, and it keeps burning the wick, and I'm down to about 370º. My coil is SS, 2.0mm, 7wraps, at about 6.7 Ω's. I just want it to not burn the wick while I get the wicking sorted out.

I just want it to not burn the wick while I get the wicking sorted out.
When I metered it after building it read almost .9Ω om my tab 21, in the BB it's showing .67Ω.
So far on this build it seems to be working ok. Set at 350º, and 7.4w. Hopefully it'll keep wicking the juice.
Well, after a little googling, seems if I stay under 380F, I should be ok, I think. But I gotta rebuild, my Ω's are moving on me, now at 8.1Ω, and firing way to hot. So I have some more work to do to figure out just what is going on here..
From what I could find in a quick search, rayon ignites at 420F, higher than cotton at 350F (again according to a quick search so don't hold me to these specific temperatures. I normally run around 420-440F using rayon and have NEVER had a problem with a burnt wick even on the occasions when I experimented at 475F and higher. Keep in mind that the wick never gets as hot as the coil because it is cooled by the liquid flow through it. If you're burning the wick at 350 and the vape is "hot" something is drastically wrong, somewhere. I don't know anything about the STM, but I would suspect a bad connection, somewhere, giving you bad results.
SS (316L anyway) goes up when heated if dry. My STM RBAs show around 1.2 cool/wet and go up to 1.3 or 1.4 while vaping. If your mod allows you to lock in the resistance that should help.
I took it apart again, kinda tugged on the coil, pushed a little, bumped it here and there, ohm's didn't budge, so I don't think it's a bad connection. I locked the ohm's, I now have the temp set at 220F, 7.5 watts. So far it's doing good.
