I got a couple of these and been trying them out. So far I like them. The most productive use for me has been to use them on brush. I cast out there, wait until the desired depth, then start my retrieve as per the instructions. My latest test was yesterday, I caught over 20 fish, and my three largest were on the thin straight tail. All three fish weighed 1.5 pounds. The water temp was 56 degrees, and the water was stained. Brush was in 5-7 FOW. My nest test will to be tight line them. I do have to admit, t first I was skeptical, but after yesterday I will be ordering some more.If you have not tried these I suggest to get a handful, I don't think you will be let down.
