Well my next big atty purchase will be whatever Dave comes up with. Been on the fence about an oddy or ithaka but I give up due to the lack of availability.
I'm not a huge silica fan but my Oddy clones work like camps as so do my genny's. I've had horrible luck in the fc2000 dept, and I don't think it's the best ceramic material for wicking purposes.
Anyways, I just hope for something easy to work with, flexibility with how I want to build it and most importantly it needs to be consistent.
