Thanks for the info Henry. The Bettencourt Baits Assassin uses those triple split rings and they do seem very solid.

I wound up pulling a retarded move and getting size 6 and 7 of the steel ones from Jann's Netcraft. I didn't pick up on the fact that they didn't say H next to them, so they were just regular swivels x( They were too big for all my baits too except 12". I think I'm going to just wait until I see some good ones in a shop somewhere...
