i used to always use gami siwash hooks. lost a lot of fish on spinners and started experimenting.

any more, all my spinners get set up with a VMC siwash with a split ring. the VMC seems to hold better than the gami, and the split ring helps keep the fish from twisting the hook out. the VMCs are very easy to sharpen and hold an edge, too. as long as i keep pressure on the fish, they seem to stay hooked up, even on coho with barbless hooks.

trebles work well, but it just seems like the areas you can use them get fewer and fewer every year, and be prepared to lose a lot of gear. where you can bump a single hooked spinner on the bottom, trebles seem to hang up every time.
