I will say after receiving a hybrid red black, now I know there is a difference.
Hard to explain, it's just so much smoother.
I still like the VTR, Coolfire 2 and the Maraxus mod, but the Provari really is a step up.
As far as Variable Wattage goes, personally I would not use it, apparently I'm a voltage guy lol.
Now if i could just build a micro coil without a torch lol, can I use a lighter only?
