I have not used a Gordy strap on my Yashica TLR, but I do have one with a string attachment on my 35mm Vito B. Although it looks rather frail, it shows no sign of failure after a couple of years of use. I'm a great fan of his straps, and have a couple of others for my Pentax SLRs. The only reason I haven't bought one for my TLR is that it came with its own strap.
