I recently went from an ego type set up to a smok T-Priv and smok Priv 8. Which coils are best for the tanks that came with the kits? I vape a lot, and want more flavor than clouds. I currently use a .4 @ 40-45W with the T-Priv, but not sure if I should use a M2, T6, or X4 in the V8. Bought all three. V8 gets hot real quick on the mouthpiece. I use the T-Priv at home, the V8 on the go as it fits in my purse. If there is a better small mod than the V8, please suggest!
