I had some new custom strings made up for my Bengal but the shop didn't put but 2 or 3 twists in it ??? I've put a few more trying to get my peep aligned correctly... My string leaches slide up and down own the strings to my center serving after about a dozen arrows??? How many twists should I have in it ???? I just got the bow shooting bullet holes on a walk back will I need to do that over again ???
