A buddy and I have been fishing from my boat the last few nights near the narrows and have had a ton of adult silvers follow our flies to the boat, but they will not grab em. We are fishing tube flies on sink tips and the fish seem to like the pattern enough to chase it for thirty or forty feet, but they all seem to lose interest before they hit. I have been using the two handed eratic strip, the quick single hand strip, and just about everything inbetween. In the last three nights, we have been denied by at least 50 fish. I can't take much more of this abuse, any advice?
