My favorite freshwater silver salmon fly, Jimi Roe. It is just a short pink body, dubbed UV Ice Dub is my current favorite, but pink chennile has been working for a lot of years. There is a single wrap of high quality purple marabou (hence the Purple Haze/Jimi H reference) and a turn or two of either pink or purple, high-quality hackle.

The purpose of a hackle on a marabou streamer is to help keep the stuff from tangling back on the line. The hackle acts like a dam to keep the marabou back.
