Most info I use is from "Spoonfishing for Steelhead" by Bill Herzog. Well here is my $.02 on the subject. I usually use 2/5 oz little cleos in gold or copper. If the water is cloudy and I cant see the spoon in 3-4 water depth I try a spoon with red coloring. Can buy them or add red metallic strip. In overcast weather I prefer the copper over the gold but both work. On bright sunny days the little cleos but off too much flash. I always carry a permament black marker pen to dull the flash. Start with a vertical stripe down the convex side. On some days the convex will be completelty black. One other suggestion to really catch fish get Herzog's book.

Good luck
