This is so confusing mate.
I've been suggested mega v2, iJust s, egrip and sub
tank mini.
Well yeah... iJust, SubVod Mega and the Ego One's are all the same thing really. A tube mod with no adjustments, the watts change based on battery life and Ohm's. The SubVod Mega comes with a TopTank mini that you can buy a RBA deck for and the Ego One's have a CLR coil option so one of those 2 IMO. It's not confusing your just thinking about it to much. People have their favorites, usually whatever they own. Other then looks and build decks the difference is very slim between a good tank and a great tank IMO. There are bad
tanks though. SubVod Mega or Ego One Mega IMO. You could look for a SMOK Stick too the one that comes with TFV4 mini. If you were going to use factory coils there is big differences but your builds are your builds, your builds don't change just the
tanks, looks and batteries mAh do.
