I am using rayon for 2 weeks now. Its great for flavor and wicking and is easy to manage, but in aqua and
kayfun i get bad taste after 2 or 3 days. Its hard to get appropriate amount into the coil, because it doesnt expand like cotton. Its more like silica wick when saturated... So it can easily move away from the coil athe the sides and that means burnt taste or its too much rayon and in 2 to 3 days you will get bad taste. 5 rebuilds, still not good. Back to organic cotton on
rta! Japanese cotton is on the way!
In magma and tobh, rayon works great! Delivers delicious taste and you can get clean taste from new aroma right away!
