I've competed a few times, but only once before with a shirt (long time ago), but I did practice with the shirt for about 3-4 weeks before the meet, which I plan to do this time.
What did you mean by having trouble touching weights?
I've heard of some guys who felt like they actually had to pull the bar down to their chest. That's what I first thought of when I read that, but I'm not sure if that's what you meant.
I still have to find someone to help put the shirt on me since the team I was with before was from a gym that closed down years ago. I wanted to go with a friend of mine, but he stopped training for powerlifting a few months ago when he hurt his shoulder (and he doesn't want to start training for it again).
If I can get in with a bunch of guys at my gym who compete, I know they can help me a lot with the shirt (one went to the Arnold classic and has a world record in the 181lb class). I just have to talk to them and see if they're going first, and second if they wouldn't mind helping me out.
I might not be able to use a shirt at all if I can't find someone to help me get it on. I remember it taking a while the last time, and (no offence to my wife) I don't think she'd be able to get in on right (but I might be wrong).
