On that last statement I would say it depends on the tank. For the aspire or kanger subtank, definitely a reggi mod. But the better the rba deck is, the better suited for a mech mod. I have a Goliath V2 tank with a pretty awesome build deck that works very good on my mech mods. Aspire nor Kanger rba decks compare. And I know there are better ones out there but I spend my money on rda's. The only reason I have a tank is so I don't have to drip and drive. But I'm quite happy with it.
