I just started learning a single ply shirt and have briefs on the way. It’s a challenge but I’m excited about getting into it because I believe my competitive career will be much longer using it. It is NOT easy as most might think. Takes far more technique and patience. There is a delicate balance in weight selection.
Personally, I think gear(particularly multiply) lost credibility due to a few who set records and obviously were given lifts.
Good work on your end. A grand is heavy no matter what you do!
