I think you might have the wrong tank for the job. I agree Kayfun 5 is great. But my Aromamizers are equally good at a different task. I never did get on with vertical coils in them (I do in my Origens) but dual 8 wrap, 2.5mm, 26g, very slightly spaced, around 25-27.5watt - pretty hard to beat.
I've never had a problem wicking them, but we've had threads on here where people just couldn't get the right side of it. I use Muji, loosely Scottish rolled (Soft, southern, Kentish roll?) - the fact that you mentioned dry hits makes me wonder if you're under or over wicking. I have never had a dry hit off an Aromamizer - probably the only tank I can say that about...
