Has anyone else had trouble with these hooks in so far as the points become blunt after a short time. During my carp and barbel fishing days I checked the sharpness of the hook at every opportunity and when people queried this answered with "I catch more fish on new hooks". The truth was I sharpened them and only replaced them if that failed. With the Patriot Doubles I find sharpening is a waste of time and the only option is replacing the fly. Any solutions out there?
