The Cadillac of bluewater fishing hooks!!! Mustad Duration hooks are designed to bend and not break, keeping the fish of a lifetime hooked up. 7691 hooks have a slight recurve as well, keeping the hook in the mouth of pelagics as they jump. These hooks are excellent for trolling live bait but work well when stiff rigged with artificials as well. The 10/0 and 11/0 sizes are THE hook to use when chasing blue marlin giant bluefin tuna.
