This topic is good timming for me I have been spending most of spring shooting and tunning arrow shelfs/pass ,I had a problem that was driving me nuts tell I figured it out I had perfectly bare shaft spined arrows that where still flirting a little coming off , I dont use self knocks so I rotated the cock feather more towards the 7 oclock position and it eleminated my problem the arrows came off like darts , kinda of a pain with hot glue knocks but well worth the effort , DC if your getting snags on the velcro give it a shot ! Plus the arrows come off quieter now !
