What I have is a Provari and some Chibi tanks. I've also just ordered some glass tanks from theecig.com. In the Chibis I use 3.0 ohm single coil cartos...and I got two Smoktek 2.0 ohm dual coil cartos with the 2 glass tanks. I've ordered 30 Boge single coil cartos without the holes punched in them...so I'll have to go to town and get a saddle valve! I also ordered 8 of the Smoktek dual coils today....wish I hadn't after reading keefers post...but oh well, I just ordered 8 thank goodness...wish me luck on that one! lol!
I've been using the Chibi's for awhile now and I really like them! They don't leak or slide, I'm just wanting to go to all glass. Glad to know I'm not the only one around here born in 1959 Richie! lol!
