I never did very well on opening day of trout season got the Line wet but never caught anything. Some years ago I found a recipe for a fly on this site the SHWAPF, swept hackle wingless all purpose fly or something like that. I made that fly with purple buck tail and blue mylar body. I fished it as a streamer and my opening day luck changed. I fish it in feeder streams that run clear and now catch fish on the season opener in the same spots that I had never caught fish on anything else in the early season. I use that pattern in different colors and fish it dry and wet and as a streamer depending. But purple is the way to go for the season opener.
