Been thinking about getting this tank but wondering if it delivers "better" taste than the Kanger stm at low wattage ? I usually run single coil 1.2 ohms, 12.5 watts on the stm rba.
I have the full size tfv4, not the mini, but I believe they both use the same coils. If that is the case, on stock coils(triple or quad), you will get pretty much no flavor at all. If you go with the TF-T2(dual coil 1.5ohm head), you will probably get ok flavor, but the tank is really meant more for higher wattage. Obviously, on the rba deck, you could pretty much build for whatever you wanted.
Edit: When I said "you will get pretty much no flavor at all," I meant if you are running the triple or quad coil heads at 12.5 watts. When you start running them up to around 70-100 watts(quad coil especially), you can get amazing flavor from the full size tfv4. I imagine it would be the same with the mini. But, since you said that isn't your vaping style, I would say your best bet would be the TF-T2 head or one of the RBA decks.
