The Slumpbuster is a well-known streamer pattern by John Barr. This version is tied on a jig hook using a new faux fur yarn available under many brand names. I have seen three: Sirdar Alpine, Lion Brand Go for Faux, and Niceec Fur Yarn, but there are probably others.
The main purpose of this video is to show the tying properties of the fur yarn. Three techniques are demonstrated: using the material like a Zonker strip, wrapping it as on a bunny leech, and clipping it from the “hide” for insertion in a dubbing loop.
