I was reading through a copy of John Goddard & Brian Clarke's book, "Understanding Trout Behavior" and found their comments on nymph design very interesting. They suggest for visibility of nymph patterns against the stream or lake bottom, you incorporate into the dressing a stip of white feather or silver mylar. They have an excellent underwater picture examplifying this. Has anyone done this and compared the number of strikes versus a dark color material?
