I have a question for opening amps with an opener. I am using ICN test and when I put the amp opener on it to do the score, I have to slowly add pressure while twisting the amp till I have enough for it to start to score. Sometimes it is hard to find the correct pressure for the opener to start to score. Many times I will put a little too much pressure on and the amp will snap open before I even start to score it. It doesn't shatter though, just the top snaps off. Anyone else have this problem? I think that maybe the amps for ICN's are a little too thin.
