Hey y'all! So I took y'alls advice and ordered a few things from strapworks, which came in 3 days! The cord I ordered, 6mm is quite a bit thicker than anticipated so I could only get two turns inside the rings, but it still seems to grab quite a bit under load. Won't be able to test it out for a while but I'm excited, thanks for everyone's help, I've put up a few pics for input. Thanks in advance!
