Just checking in. Had a forum member send me some rayon in a care package and I worked my way through 4 of my rta's with it. I am impressed. I have been using mostly Kho Gen Do cotton for years and now I am a rayon convert. I still haven't figured out how to get the rayon to wick properly in all my rta's but in the Doggy Style, Skyline and my Kayfun Prime it was a breeze to wick. I like the clean taste and the fact that the flavor is stronger than the KGD. It is not a huge flavor difference but it is obvious. Got a box of Rayon on the way. If I can figure out how to get this to work in my Hurricane rta I will have this thing figured out. I even managed to wick my Tilemahos Armed Eagle with rayon and it works great. I haven't had it long enough to test the longevity but the flavor boost is enough to keep me interested. After reading some of this thread I don't find it very hard to get right in most of my rta's. So far the Hurricane V1.2 is the only sticking point.
Welcome to better vaping with rayon!

Some get it right quickly, for others like me it took a longer time to get it right. And as you have found, not all atty's wick the same, it's a learning curve for each one. For "me", the two most important tricks are using more rayon in the coils then you would with cotton, rayon shrinks/settles, use to little and it will loose contact with all sides of the coil as it breaks in. Second trick is thinning the tails more then you would think, I thin mine down to 20-25%, some folks thin more then that and the rayon will still feed juice like a fire hose, it's amazing stuff!
I use the Steam Crave Aromamizer V1's and V2's with the two post decks. One thing that has worked well for me is when I thin the tails, looking at the coils from the side, I make the cut at the top leaving the tail on the bottom. This leaves the cut ends of the rayon on the top and exposed, I do that for two reasons,
1. It makes for a cleaner bend when tucking the tails under the coil. I'm able to fold the tails under while keeping the fibers in a straight line, not twisted like a braided rope. Straight fibers feed juice easier then twisted. It also reduces the bulk of the bend because I'm not folding over cut ends as it would be if the cut was made at the bottom. I wanted to keep the bends of the wick from laying against the walls of the chamber once I put the deck back in the atty and away from blocking any air flow from the side air feed holes.
2. With the cut ends exposed at the top, if I over stuff a coil I can pull a few strands at a time from the coil with tweezers until I get the right amount. I rather over stuff and pull a few strands then under stuff and have to rewick. Although I've used it long enough now that I rarely have to pull strands anymore, but it's nice to be able to tweak it rather then have to rewick.
The first time I experimented by cutting the top of the tails I wasn't sure if those exposed cut ends would be feed enough juice to keep up with my vape but rayon is just so damn good at feeding juice it's never been a problem, my wicks are always nice and wet.
But, what has worked for me may not work well for others, we need to experiment and find what works best for ourselves and for the attys we use. One thing for sure, once we find the sweet spots, rayon rocks!
