"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."
I agree water level, size and clarity are key. I usually downsize to a small steelhead bugger..........maybe even as small as a sz. 10 at times, bucktail streamers which tend to appear sparcer in the water etc. However I do like Pine Squirrel zonker skins
and they make some dandy downsized Zonkers for low, clear or pressured water conditions.
I should have put the "Creek Chub" on the list
it came in right after the darters & dace as far as quanity. A bit larger size also, which is fun. I am sure Steelhead give them a wack now and then. One of the chubs "creek or river" also had a purple upper body sheen if I remember correctly.
Maybe someone can post a picture or drawing of one ?
