Have to agree with most of your observations on materials and flies. And the development of patters in the Great Lakes seems to back them up also. Flies with rabbit strips and marabou seem to be very common lately. One deviation I can see, however, is in extreme low and clear water conditions. I seem to do better with very small un-obtrusive patterns with minimal motion in these conditions. Small white streamers with stiff polar bear wings are my bread and butter during these times. With that said, I would much rather fish a big rabbit strip pattern in high water.
I was wondering about the origins of the weamer name. Very interesting. By the way, Iím still working on the tube version of that fly for the lower Niagara. I will have to get some pictures for your approval when I get it done.
