Been playing around with these sickle hooks i got off Pete. Tell ya what i'm liking them. been using the 4/0 and 5/0's for the channels and just finally got to use the 10/0's for the flatheads. Far as using the 10/0's for the flatheads go, I had 3 of them that started running on their own and set the hook there selves while the rod was still in the holder. but the rest I set myself. It is nice to know you have a double action hook you can use either way, depending on the conditions. No more having to wonder if you choose the wrong hook that the conditions will present to ya. Far as the channels, most hooks will work, but again, it is nice having that option to either set the hook or let the fish set it. Most times a channel with that pecking bite, a circle will be fine. But having the option that the sickle hook offers just adds up in my favor. You add in the fact that these sickle hooks are razor blade sharp, not taking much to pierce something only adds to the quality of the hook itself. Personally, and this is only my opinion, Matched against the kahle hook style, the sickle will win everytime. I've probably used the Kahle close to 20 years or better.
