Anyone tried this jig before

I have been interested in trying the jig called the x-change jig heads by lindy just looks kinda of cool if you have tried these out let me know!

I don't understand paying that much extra to change weights verses tie'n on another myself?

I've tried them as a matter of fact I have a bunch of them. Todd Huckabee gave me a few at a crappie semi at he spoke at. They are good strong hooks and you won't be straightening them out to save them from a snag and they are pricey but if you look around you can find them a little cheaper. I caught them on clearance at bass pro and stocked up. If you like them then I would give them a try.
