ya I am with hawg. why not a 90 degree hook in the sickle?
Here is an easy way to look at it. When the bend in the hook is at 90 degrees the steelhed or salmon have leverage and can use that to dislodge the hook. Altering the bend to 60 degrees means that the fish has less leverage and a harder time throwing the hook. Fly fisherman have found this and alter their approach. Instead of tying most flies on a long shanked spey hook
they use a shank fly like this
The octopus hook in the shank fly, like the 60 degree jig hooks, have less leverage.
All you need to know is, these hooks are awesome and will put far more fish on the beach than others!
