Hey guys. So I am somewhat new to vaping and I am having leaking with almost every tank I have. Especially my pro tanks (2, 2mini and 3) I recently realized that there are some minor differences between the bases of the three (of course the mini) and I am sure I've mixed some of them up. I hope this is the only problem. I have on order 32 ga kanthal to rebuild my attys until then I was trying to find a breakdown or side by side comparison of the 2 and 3. Any help would be appreciated!! also what resistance coils should I build iyo??
