The folks at QuickRig have some neat stuff, as you’ve noticed further up the page with their offset hook rigs. They also make a couple very nice series of snap swivels. They all feature ball bearings, are made in Japan (not China…). They run a wide range of sizes to fit most applications. They make both a tournament style rig and also a corkscrew connector. Both are very well constructed, and reliable. Come in packs of 5.
