Size 14, yellowish elk hair caddis fly. I fish it 90% of the time. Spring, summer, fall and winter. The dubbing on it is some synthetic stuff I picked up at LRO to tie October caddis' with, but once tied they look like a sparkling yellow color. I personally don't tie very well, so I just keep my fly in the seam with the rough water and only fool the dumbest fish.
