IMO the eggs from the species you are targeting are best (what Dave said). But it also kind of depends on the species you are targeting. If it's Steelhead then my second runner up are Coho eggs, third are probably Chum, but every other year I seem to have an over abundance of Humpy eggs, which have caught many fish also. I also believe that you'll have greater opportunity if the eggs you are using come from the river system you are fishing.
