This set is rigged with 4 sets of swivel rigged wire leaders that allows for quick change of lure. Many Wahoo Anglers crimp straight to the lure or use a haywire twist, with this rigging you can switch colors, sizes, lures, etc on the fly without having to keep the leader with the lure. One leader can be used for multiple lures. It is the way to go to keep organized on the water. The Thetis Bank is famous for the long range san diego fleet and right out side of MagBay and that is why they named this kit the Thetis Bank. It works great all over the world but is a killer MagBay combo kit for the pacific.
