Why do you want a genesis style RBA? They are widely known to be one of the most difficult to set up. What would you think of an RDA like an IGO-L? That would be much easier.
If your protank heads are failing so consistently, there must be something you are doing wrong every time. There are plenty of tutorial videos out there for you to follow and I am sure that is what you are doing, but not quite picking up on some important detail. The other possibility is that your device is not making good contact. What is it by the way? I know you said cgr18650ch earlier, but is it in a mech or something else?
im with cloudz, wait to try the gennies, or you'll be joining me in my stint in the booby-hatch.
Although, i must say, for its price, the little Did clone is VERY easy to set up; it was the first time i ever succeeded with the 'pulse method' for gennies. Igo-L, like BeRight here suggested. Two posts, one deck, and a top cap. Easier to set up.
