I had an opportunity opportunity to fish some flies tied on the #12 - 051 hooks at a local creek using a full flex DT Mutant. I landed 4 fish but did not get a solid hookup despite a crisp deliberate hookset on 5 or 6 fish that quickly came unbuttoned.
The 051s have that profile with a straight horizontal hook to the point from the bend but is slightly offset to the side of the shank.
The 062s have the hook that is in line underneath the shank but the point is slightly upturned and just looks like it would be harder for the fish to shake loose. I think I need to try some #14 062s.
