I agree with Addicted that the sickle octopus hooks are the way to go for trolling. For the first year I tested them I had a 100% hook to land ratio. When you hookup, you really stick 'em good with the long straight hook point, and with barbless that helps keep the hook embedded by limiting the rotation of the hook during the fight. They don't wiggle back out as easily.

I've also never had a hook break on me. I think it's safe to say a weak batch was put out and the problem was fixed.

My only beef is that I'd love to see them made with a high grade stainless wire for marine use (like some stainless Mustads), and they don't stay sharp for very long. Make sure you touch them up with a sharpener often.
