Skipjack,
Roger on the mushy fillets. And they are bony as heck too. That's why the Caribbean folk do that trick of beating them up with a rolling pin or whatever, then cutting that slit in the skin and squeezing the meat out, then making among the best fish cakes that I have ever tasted. Remember, their diet is mostly shrimp and crabs and that makes their flesh delicious.
Bonefish are great fighters, eaters and absolutely wonderful natural baits for blue marlin and humongous wahoo. And as I noted in my first post, they are tough as hell and will literally stay together and swim great all day long.
Here's another long lasting bait that often isn't when rigged the usual way. I use the Quick Rig Bait Bridles with circle hooks on these. I don't show it here, but the bridles are also available with "chin weights" mounted on one arm of the Bridle itself. There is a full discussion on this on my website in the "Ballyhoo!" article. The mackerel can be either the Pacific or Atlantic variety, or Spanish.
