Re: Upstream or downstream....
I have almost no real preference up stream or down stream, I do however, usually walk up stream to stay out of their field of vision. The most important factor in determining presentation style is the likelihood of lining the fish or spooking the fish by floating your fly line over the fish instead of the fly. A downstream cast has almost no chance of lining the fish and therefore spooking the fish prior to the presentation of the fly.
