I am looking for a very easy draw and huge vapor production in possibly a cartomizer or tank. I've tried the eGo tank with a regular and low Res Tank atomizer. While the low Res Tank atomizer offered significantly better vapor production, both required suction that rivaled a good Hoover vacuum cleaner. I currently use a Low Res eGo Type A atomizer and cartridge with 100% VG juice. The eGo type A low Res atomizers are getting hard to get and the Type B's I tried all leaked due to not enough packing in the cartridge.. So I'm looking at alternatives. I had to go with 70/30 pg/vg to use the tanks as the straight VG was to thick. For me a big part of what makes vaping satisfying is huge vapor production, hence my love of 100% VG juice. In all likely hood, I'm looking for the freakin holy grail of vaping but my basic question is what device or devices produces huge vapor, has very easy draw and maybe can use 100% VG?
