Z-Lon, I guess, is the most popular now but I have never thought it looked all that great. Pheasant tail fibers are popular, Antron, cut off hackle barbs, biots, La Fontaine liked marabou, and I've seen a lot of tiers use CDC. Shane Stalcup marketed his "Trailing Shucks", which were small thin strips of plastic in various colors, but they really never became popular.

What is your favorite? I'm still looking for my mine.
