Tyrant Replacement Tails are designed to be used with the Tyrant jerkbait. They may also be "welded" onto other existing soft plastic lures such as Bulldawgs and Super D's. The preferred method is by using any waterproof fishing flue. The Tyrant Tails can also be used as trailers for jigs, bucktails and jerkbaits. There have been reports that these tails work awesome when jigging for halibut!
