You are right about the line thing Os - but I was talking about fishing line, not clothes line . ... We agree on this subject Mike. There have been other scientific studies on fish vision and reaction that I just think often lack the common sense and actual river condition fishing experience that all us hard core fishers have garnered over the years. We know what colors work in particular conditions in particular watersheds - despite what is 'determined' by controled tests. My $0.02 worth too.
