I had bought the new 4ml cartomizers for my boge leo but found them to be too high a resistance at 4 ohms . That resistance is good for a provari though so recently I ordered a 510 battery to Leo atomizer adapter and it works good . I vape the Leo 4 ohm cartomizer at 6 volts on my provari and it tasted really good . Vapingzone also hase 2.4 ohm cartomizers that they label LR for the Leo but I call them the standard resistance cartomizers .
