Those of you who shoot Crusaders, what nocking point setting have you found to be the best??

I put a new string on my Crusader and am having trouble getting good arrow flight. I have by brace height set at 7 1/8" (between 7 1/8 and 7 1/4). My Crusader is 52# and I'm shooting 50-55# POC arrows cut to 28 1/4" with 125 gr tips.

My old string had the nocking point set at just under 1/2". The same settings just aren't working on the new string. Or do I just need to let the new string get more broken-in??
