Pick up some #5 and #6 Blue Foxes, since clear water and sunny weather will be playing a role, you're better off with anything BUT silver blades, too much flash will spook the fish (most of the time), Brass will work great on the somewhat cloudy days, Copper if it's a little sunny, or try to find a weighted spinner with a black blade for the extremely clear, sunny days.
If you don't want to worry about all these different colors of blades, you can also match the size to the conditions, for extremely clear days and clear water, you can get away with a #3 or #4 with a Brass blade, it will work more effective for Steelhead than a #5 or #6. Steelhead are more curious than a Salmon, a Salmon has to get p'ed off which comes from the sight of another fishes eggs or getting to the lateral line, which is generally the result of using a big spinner or Kwikfish.
But like Shane said, sometimes you can't work a lure in some situations, and that is where the Corkies and Yarn are used, I only use yarn for steelhead since they actually eat it and it is a waste when used for Salmon.
