A tip from my days as one paranoid about old camera straps and strap lugs failing: use two straps; one attached normally, the other attached to two a keyring around the tripod screw stolen from an eveready case. It's not pretty, or overly comfortable, but it would work. Ironically the only camera I've ever done this on is a $30 Yashica 35, I don't bother with my $500 Leica.
It is better to just forget such paranoia and get on with using the camera; easier said than done, but if you can't make photos or enjoy using your $5000 camera it is better to leave it at home and use a cheapo.
