I love panther martin spinners,
I have caught bows, brookies, browns, steelhead and cuts on them. Some smallmouth have also hit panther martins for me.I like the yellow bodies with dots and a silver or gold blade. Black body with yellow dots also work great. They work on so many rivers in so many states for so many species. The blades spin better than rooster-tails. The only panther martins that don't work as well for me is the ones with feathers on the shank of the hook. Others out there might have had better luck than me but I always buy the ones without feathers.
