Hi Smith, looked at these? http://shop.flybubble.co.uk/gin-glid...ing-Comparison though you don't say what the application is and although these things have a HUGE safety margin, the wrong one in the wrong place can be deadly. What you need it for, need to shock load, be strong across the axis, be self aligning? Also boat yards can have good kit, but say what it's for first, "there are bold climbers and there are old climbers, but bloody few old bold climbers".
