I run my 3 Nemesis mods (not clones) exclusively with 18650s and Kicks. Over time I've found that that is just the battery setup I like. To the OP - I also have a 69 (another Atmomixani), V3Tronix Flip, and Vaper's Knoll Gnome that all work in that configuration. Atmizoo's Roller will also work in that config, but you need to also have their RD-T2 ring. I am somewhat surprised that more recent and very nice mods (like the Stingray which I had briefly, and the GUS Lord) cannot accommodate an 18650+Kick. But I'm guessing 3/4's of mech mod folks don't use kicks, and then probably only 1/2 of those use 18650s exclusively so it's a small market I suppose.
