I prefer the Owner Twistlock Spring on Shanks and the Mustads hooks. Have never had either bend on me. The Owner Twistlock SOS's are fantastic for holding frogs,lizards, and flukes on the hook. I have yet to have a an artifical bait slide down the hook when using the Owner Twistlocks. However, they are expensive, and I only use them when going for Big bass. If Im just out fishing to put something in the boatit's Mustads all the way!
