It's a screw lock I'm making myself out of 175# single strand SevenStrand wire and as to hook up ratio, ask anyone that's been out with me....don't miss many rigged this way. BUT, I've got the appropriate rod, reel and 30/6 spiderwire, the later of which I deem key to success rate with any plastic baits.
Here's a pic of the hooks and screwlock.
