In a recent topic Castwell confessed to having fished for a great while with a white fly that produced no fish and then discovering that the end of the hook had been broke off earlier. This confirms the notion of check your fly. I, like all experienced fly fishermen can verify the value of this addage. When I find The fish have suddenly stopped biting or I just can't seem to hook them I've learned to check the fly. Almost invariably there is something wrong with the fly - its been wound up in a knot, missing, the hooks end is broken, or its just mangled beyond recognition. I'm sure most of you figured this out more quickly than I did but eventually I did catch on.
