Well I found I can order the actual String Sling from their website, but by the time I shipped it here it would cost about $50. I went to town and spent $14 on pieces and with a little sewing I have something similar that I think will work. The hook rests against the d-loop and balances well there, and all I need to do is raise the bow and the hook detaches. I will cover the hook in moleskin or something to make sure it doesn't click against anything.
