Redoing the Manns stretch 30's changing all the hook split rings to 255 lb SPRO
taking off the lip split ring using 105 lb single wire and a 300 lb SPRO swivel. Ya its work but worth it
Interesting.. you had many split ring failures? I've never had a problem with them, the hooks yes, they're weak and will open quite fast if the drag is tight, but I'm yet to have a split ring fail on me. Usually end up getting water inside the stretch 30 or they bust up the swimming after some fish.
