Here's another from the Chris George Polychromer series, a Chinook Willie Gunn.
Here's a classic colour combo from across the Atlantic. It's a great adaptation for Chinook salmon. The tail is Marble fox, dyed sunburst orange, Fluorescent flame UV Red marabou with UV Black covering. Add a little UV Amherst, long flowing hackle tips, and loads of flash for a fly that's pretty hard to resist.
