FWIW.......Zap has merit to his post about wading up to his nipples and casting back and fishing the skinny water.I watched a video with Dec Hogan doing the same thing.He was wading the middle of a river and casting to both sides of the skinny water,Hmmmmm, new strategy noted
It does work. I was streamer fishing an interesting set of water on the stave, were I was able to cast out to the current seam and have my fly swing into a "rip". I had several hits, but they eventually stopped. I then casted towards shore, swinging in the opposite direction and was into fish again. Just changing the fly orientation made a big difference.
