Thanks Don. I guess I will have to try some nymph hooks and see if they will stay up in the water column enough for the type of fishing I'm doing. I'm still landing most of the fish on R50 hooks but I have to continually bend the hooks back. Hard hits by 10 lbers tend staighten things out. Most of the hook ups are in the corner of the mouth suggesting they are taking the fly on the turn. I'll go tie some flies on heavy nymph hooks and do some experimenting.
Cheers, Rob
