At the top of any list for steelhead flys should be whatever you use on top for me that would be some type of a muddler variant followed by the original skunk on light wire so it can stay up on top 80% of the time. the rest don't have names but look a lot like Spey flys tyed in subdued colors smacking of tradition amd always fished with a dry line.
Unless its decjanfebmar. in which case I'll use a sink tip and some big ugly thing made out of Marabou ,whatever that is, in too bright of colors.
