i have a reasonably new slingshot safety system and it has quick clips and havin a bit of nautical background i know they are trouble they fold back on themselves and unclip cauzing serious problems. trust me this is serious i have lost my whole kite b4 the chicken loop stuffed up and came out so i body dragged back to shore and thought i would use my safety nope the whole kite took off up the beach (thnx to the guys who grabbed it 4 me) but yeah be cautious of these clips they are a simple carribenah (bad speller) like used in rock climbing. stay away from these scary stuff happens
