I appreciate the tip brother, but I can't see in sixteenths.... I think you are right. Come to think of it, that usually happens on bows before I mark a nocking point. Of course, sometimes I don't install one of any kind and just sort of eyeball things till the arrow looks like a right angle and then fire away... If it is for serious shooting though, I definitely install some kind of nocking point on the string. Keeps things from stringing up and down the target.
