can someone tell me why a D loop/ string loop whatever ya call it,has to be so agitating?? I mean it seems like everyone I get put on ends up twisting, that would be ok if it didn't end up screwing with my peep. Anyway, I got a new tied on today but it seems a bit longer than the old one. and there is more space between the knock points. does length of the loop affect draw length or anything??
