I have used wiggle warts probably since they were first introduced, not trolled but cast in water 20 ft and under. I have caught countless eyes on a slow retrieve in shallow water around the islands. Don't forget to try them on the reefs They are magic in the evening and slow and shallow. I still have 5 or 6 of each color made. Never used the magnum much just the standard. One of my favorites is a little silver scale pattern Flat Wart. One word of caution if you get these out and use them make sure to protect them from prolonged direct sunlight especially if they are laying in a clear box and closed up. They will heat up and split down the back.
