I'm switching from LR 510's on an ego to 5 volt vaping on vari volt Tekk mod: voltage range of 4.5, 4.8, 5.2). I loved Eastmall Lr atties. I'll still use those on my ego pass-through. Now I'm looking for the best mid-range 510 atomizers in the neighborhood of 3.1 ohm to 3.3 ohm. Best atty in this ohm range (manufacturer brand) & vendor to purchase from? Also if anyone knows where to buy the best 510 cartomizers for 4.5 volt vaping that would also be much appreciated. Thanks in advance.
