Hey FB -
The sickle hooks work just fine on bass, crappie, and goggle-eyes, though I don't see any real difference between them and a hook with a plain-vanilla bend. However, there's something about unleaded jig-hooks that doesn't feel quite right. First of all, "Why?"
Second, the offset just might effect your ability to get a good hook-set. Don't know about that for certain, since I have never used one (And don't ever intend to!). If you have a local pond/lake whwere you can experiment, you might compare strikes to solid hook-ups with each type (jig-hooks against conventional styles) in similar flies. I'd be iterested in the results (Even though I'm pretty certain they wouldn't convert me!).
