I don't tend to put too much emphasis on any one pattern but more on the size of the pattern. For high stick nymphing, here is a simple rule of thumb; the lower and clearer the water, the smaller and more subtle the fly (pheasant tails, stones, hares ears and light colored eggs). In these conditions, the fish get a good look at your presentation. With more stain and flow, go larger and more animated, (Buggers, ESL, or big, leggie stones). I'll even go to bright, thumb sizes balls of steelhead yarn in a bait holder loop if the water is really off colored. Here you need something that will grab their attention for brief period of time.
This rule holds true for the swung fly as well.
