Sluggo becomes hot lure for bluefin. I saw with my own eyes how effective it is for bluefin as well as how easy it is to fish. After searching for and experimenting some sluggo types of lures, I concluded to carry Ronz and Bill Hurley lures at my shop. I found Ron and Bill are avid fishermen themselves and their products are results from their extensive testing on the water. Ron said he caught as many as 7 blueifn with RonZ on a single trip. Ron used to use 3X and 4X Mustad hooks for tuna model and he is using 3X and 4x Gamakatsu hooks now even prices become higher. I told him I wouldn't contact him if he still use Mustad hooks jokingly. RonZ lures are originally designed for striped bass, but they found tuna love them and most tuna popping/jigging fishermen fishing Cape Cod carry some type of sluggo and RonZ lures are very popular. I saw some boats use only this kind of lures for bluefin. I am thinking about going on an overnight trip in Gulf of Mexico to test these lures as well as some other lures for yellowfin. But it is not easy decision as bluefin bites continues out of Cape Cod, MA as well as out of Cape may, NJ now.
