If this is common knowledge, I'm sorry, but thought I would throw it out there. In my tank rotation, I have an EVOD, T3S MT3S and a PROTANK. I love them all for their own reasons. I have been buying nothing but T3S coils, and they fit in every single one of these tanks, and work great. I did keep a few EVOD center pins handy to swap onto the T3S coils if I want to tighten up the draw a bit. Other than that, same coil, four different tanks. If anyone has seen different characteristics between these tanks, I would be interested in seeing if mine coincide with them. I am obviously a kanger/bottom coil fan. So I would like to keep this thread on this topic. Most of these type posts turn into people going back and forth regarding top coil VIVI NOVA and the like. I've tried top coil tanks, and don't care for them.
