I don't have hands on experience with these, but am also needing some for the same reason as dogzlife. My vari volt is on the way. That being said, I also just ordered HV joye 510 atties from clouds of vapor that are supposed to be in the 3.1 - 3.3 ohm range, and I just received Bauway 2.8 ohm atties to try when the
device arrives. I also plan on trying my 510 cartos on it, as well as the 2.8 ohm
joyetech cartomizers that I currently use on my ego. (I really like these by the way. Taste like dripping).
I've loved my Eastmall LR 510's on the eGo, and if the above atties prove to not be to my liking on the mod, I'll try Eastmall regular 510's as a backup plan. I've also read that some veterans like 910 atties and BE112's on the vari volts, so I'll experiment if the 510's prove unsatisfactory. I hope veterans chime in here and offer their knowledge and share their vendors and atties of choice.
Thanks to all who contribute.
