I have evods and Protanks and have tried every possible atty switch combination, eventually rebuilding my own 1.7-1.8ohm attys using 3mm silica wick and no flavor wicks, getting a "Punch in the Face" flavor using the rebuilt atty's in their original tank.
If I had to choose I would have nothing but Protanks and with my own atty rebuild. I imagine I eventually will be all Protank with a few evods for testing juices as I gift out my old eVod setups to relatives and friends to help them on the right path.
I like a lot of string juices that crack even the Evods so I figure why not stick with what works for me?
My point is, different strokes for different Folks, and all that matters is a great vape that keeps you off the cigarettes and affords you the most enjoyable experience you can have. Protanks do it for me. Find what works for you and stick with it!
