I'm a lot like you. I have a lot of trouble even catching fish. Thats why I wrote in a previous response that I was kicking myself that I didn't try wet flies sooner.
I was catching fish on 80% of my casts! Now fishing the same type of fly all of the time would probably get a little bit boring, but its always a good standby when things are slow or you can't seem to match the hatch.
I guess we need to learn to think like fish!!
So what if I don't catch a fish! I'm standing in a river waving a stick. It doesn't get much better...
