I just purchased a pearson recurve at a yard sale. It says 60amo on the handle. I've read conflicting info on the web. Some say to go 3" shorter then amo while others say 4" shorter. I've always gotten my compound strings from 60x custom strings but I'm not sure which of these I need either. www.60xcustomstrings.com/recurve/ Is one of these better then the other? I've heard that dacron is the way to go on older bows. Thanks for any help. Looking forward to trying traditional archery.
