I bought a bunch of hammered diamond jigs from an internet retailer and while the jig seems to be of good quality, I am not happy with the quality of the hook and swivel. I will be using these jigs to fish for tuna and am worried about them crapping out...especially this time of year when the tuna are a bit bigger. any suggestions on how to replace them? Seems like all of the quality swivels have welded rings which I wouldn't be able to attach to the jig and 200lb split rings are huge??? I thought about just taking of the hooks and attaching assist hooks from a butterfly jig...any suggestions? thanks
