I still get reduced vapor and 'coil crud' after 3-4 tanks, regardless of cotton or rayon - not sure what I'm doing wrong.
This is with 1/16 or 5/64 coil, between 1.4 - 1.8 ohms, running 10-12 watts on a Provari on the Russian.
I'm a bit behind on my reading, forgive if you've gotten it solved. I had a similar issue initially until I got the wick density figured out. If you're not stretching the wick like JeremyR shows in his video, its pretty easy to use way too much wick than necessary. Just use a lot less. Basically keep reducing until you get a weird metallic taste after initially starting out with everything being good. You've now found the point where the density of the wick after the last of the air between the rayon strands works out (half hour or so after you first wet the wick) is too low and the top of your coil ends up dry which is what produces the metallic or burnt taste. Wick with a bit more than that and you should be seeing all the good things folks are talking about in this thread.
If you use way too much you end up never really wicking any juice to the center of the coil. But rayon wicks so well that just what's in the edge, at the shoulders, is able to provide more than enough juice to keep the entire wick moist enough to prevent really dry hits. But the dryness at the center is what's causing the gunk buildup so quickly. At least it was the case for me.
