Genuine TS (Tournament Strong) Limit weights. These weights are the same weights the elite anglers have been using for the past 3 years. If you are a seasoned bass pro or someone who is trying finesse fishing for the first time you owe it to yourself to try these. Sure you can spend a lot more for tungsten but does it really help you catch more fish? These weights have a 2 ball glass rattle in them. Your going to shake it anyway why not add an attractant (sound) the same sound a crawfish makes when walking across the bottom. If these don't make sense don't try them. But just remember the anglers your fishing against are using them. I have elites that buy once a year, and they tell me these are the best value in bass fishing tackle. These elite anglers buy 100 weights ($50) before their tournament season begins. They don't think about it, it's the only drop-shot weights they use. Does it help? It helps a lot more than a plain lead or tungsten weight does.
