I will post a pic next time I have it apart... And yes, I'm treating out the same as cotton...

Rayon wick, better flow, flavor, saturation and Nic Hit!

Ok, that solves why it's not working as expected then, no worries, when you are ready for a rebuild, just post.
Cool, thank you... It works now, as long as I take a couple primer puffs and don't go above 17 watts... I would love to be able to try it at higher wattage though.

So, I've been very happy with rayon lately, but I'm experiencing something that's mildly concerning.
I've got a stillare wrapped with dual 24ga Kanthal, 2mm ID, clocks in around 0.33 ohms on a mech; around 10 wraps. My issue is that the coil is retaining a lot of heat, and continues vaporizing (very slightly, but consistently) for a solid 2-3 seconds after I'm done. I've even taken to inhaling for a second after releasing the button, but it'll still keep going for a second or two after that.
I've tried a 3mm coil around the same resistance (maybe a wee bit higher, around 0.35), but then I run into ramp-up time issues. It's not an instant fog machine, but it's only delayed a half second or so with the 2mm. I should mention that I'm using a chuff-style cap on the Stillare, and the thing is crazy airy.
It's confusing because the coils stayed clean for 10-20ml, then started to darken in the center, now they're fully dark (but not full-blown gunky), and the wicks are absolutely pristine with no darkening. There was never any off-taste when I wicked it, meaning I don't seem to have used too much rayon. Is the after-burn related to my wicking, or just using a lot of thick wire? If anything, it seems like maybe a bit less density might help, but I'm not sure. The after-burn is my only complaint, so I'm not really in a rush to rewick.
I've got a plume veil (also chuff'd) running 0.44ohm 26ga dual coils, also 2mm ID, that's like a commando vape: Instant heat, no after-burn, and generally a silent fog machine. So I'm definitely getting better with rayon, but don't have the sub-ohm/high-power experience to diagnose what's up with the after-burn.

Thicker the gauge the longer the ramp up/cool down time. I have the same issue when using 24-22g
I got tired of my mod getting hot and staying hot, and also the after burn.
So i switched to 30-32g parallel for regulated devices, dual parallel on my mech. Instant heat up, no heat retention. I can make dual parallels that are FOG machines, and the flavor is still great.
Just wicked my first coil with rayon. 9 wrap 28g ni200 registering .16Ω atm. Twisted the rayon and shoved as much through as I could without wrecking my coil...that's the correct method right? Forgive me, I can't read 955 pages today XD
EDIT - BTW, first time I've felt like I got a nicotine buzz off 12mg from a tank...is it just in my head or is this for real? Kinda awesome, glad I stopped by Sally's finally yesterday

That way works fine. Most of us are either using the double strand method, or the pull and squeak method. And you can NOT forget to trim the tails. There is a video by JeremyR that shows how to wick 32g without wreaking the coil.
Try thread searching keywords like, bump, double penetration, tree of life, tails, thin...
Most of my current builds (Mute X, 22mm Tobh, 29mm Tobh) are 24g NiChrome 80, 2.9mm ID... anywhere between 0.2 and 0.35 ohms. The coils do retain a lot of heat, and I get quite a bit of "after-burn" as well. Even in the Mute X with AFC all the way open. The coils do tend to get a little crusty, but not so much as to affect vapor or flavor too bad. I just leave 'em be for a week or two, then I pull the wicks and dry burn. The heat up isn't instant, but it doesn't take long... about the same as you are describing on your 2mm build. As for diagnosing an issue, I think that's just part of the game when you use heavy gauge wire. Larger mass is going to hold on to the temp a little longer.
I do tend to pulse my fire button a bit... 1-2 seconds on, 1 off, 1-2 on... etc. to help control the temp a little (especially on a fresh battery... not so much once the battery gets knocked down a little). I do have 26g NiChrome 60 in the Hobo and the Orchid V2... they are a bit less prone to "after-burn".

All of my rayon builds haven't been VERY tight in the coil, but the the point where if I were using cotton I would have gone "D'oh...too much" So far just because I love building coils and testing - I've used them on 1.5, 1.0, 0.8, 0.5, 0.3, 0.23 and they've all wicked well. I've had a few issues here and there at the beginning not having enough but now its just awesome and for the first time my drippers look like they're wicking, when I pull the cap off to add more juice, the wells are actually empty and the tails of my wick look pretty dry. Cotton always left a pool no matter how I adjusted the tails.
Twisting up rayon to get it through the coil is not the way to do it. Yes, you can twist the end you start feeding through, but the rest of the piece should have nice, straight fibers going through the coil and trim off that twisted up piece. When the density is right you'll hear or feel a "squeak" as it's pulled through the coil. Typically, it takes more rayon than cotton when wicking a coil because rayon shrinks when wet versus cotton expanding when wet. The key is full contact with the coil when the wick is wet and check after a tank or two. Trimming the ends down to 50% or even less, close to the coil, will further augment wicking. I know 955 pages are a lot of reading, but search the thread and you'll find some great photos or check out JermeyR's blog for some great photos and "how to" information.
I've gotten a nicotine buzz off of 6mg using rayon, as have many other people, so it's not your head. Rayon does wick far better, and produces better particulant/droplet sizes than any other wick. That results in better nicotine absorption and superior flavor when it's wicked right.

I press my palms together around a strip of rayon (Like I were praying) and roll my hands back and forth. It doesn't roll the rayon itself it compresses them so the fibres are still straight, just tighter. Works well every time for me.
I just twist up the end, and then I make sure to snip any portion that I touched off so I don't worry about any off-taste from it... including the part I twisted
I "pet" it slowly and gently stroke, between my fingers until it looks nice an uniform, then twist one end, add a little saliva and twist again, thread it up and trim away. I have managed to over trim once or twice, not that it didn't wick like champ but there was too little in the wick channels and I ended up with leaks. It is a bit of a balancing act.
I think all wicking is a balancing act, but fortunately rayon seems far less temperamental than cotton
Its Completely different than cotton. Using it like cotton will lead to failure.
