I've been using my provari mini with 510 BOGO cartomizer tanks. I tried using a aga-t rba but just can't seem to get the hang of the rba's! So Im think of socking with the cartomizer tanks, and just wondering would 1.5,2.0,2.5 ohm carto be better? My cartos have 2 punch holes in it but thinkin maybe getting ones with more holes or punching bigger holes
