I agree with Ford Fenders. This last week Iv'e been fishing for three days with lots of fish on, aggressive hits on leeches and other big flies, mostly with a fast retrieve. One evening I had hard bites almost every cast for a while but only really stuck a few. Others would hit hard and jump twice with 30 feet of line still in the water...not much hope on those. The next day I had a lot of hits where i would just have afeeling there might be a fish there, I would lift and it would be fish-on! I also had a few foul hooked as FF said. Just keep on keepin on and be happy for every fish you get.
