I believe these were designed by snook legend dave justice, but believe they were sold and the quality went down. I have never used one as they didnt look to swim very good(kind of on its side) plus expensive but they do catch. I believe the idea is you can use lighter leader as it deploys that hook and also helps prevent throwing the hook. I like just a jighead with a big paddle tail they are becoming easier to find NLB makes some nice ones but they are kind of pricey too.
