thanks for all the replys guys, sorry I haven't got back to check the post. anyways I do believe it was the juice, I have this cov butterscotch and it is just a picky juice. even in my gennys I had flavor issues sometimes. anyways I have now used my 2 other flavors in the reomizer and both taste awesome with the cotton, couldn't be happier! I also tried some german silica in the rm2, thinking it might last a little longer so I wouldn't have to change it as much, no go, the flavor was nothing like the cotton. its cotton for me until something better comes out. before buying my blk wrinkle reo grand I had purchased a kayfun lite the day before and now have that set up with cotton as well which is also performing awesome. although I love the reo I still like to use a tube mod with a nice atomizer, but I do find myself liking the reo more and more each day. I do think that the flavor of porous ceramic in a genesis device does have a slight edge in flavor imo, but what I think makes up for it in a cotton wick is the quickness of the vape. with a ceramic wick the heat sink kind of was a hassle, you always had to take a primer vape before the real vape, with micro coils & cotton the vape is instant. all & all I do like this set up better, thanks to all who have posted on these set ups, making it known to me.
