Hey Zach,
The name of that salmonfly is called the Terra Nasty…I think it is made by Idylwilde Flies…great pattern out west.
-just a little info for ya
Love that pattern Zach. Where can I get the specs for that one. I spend the first two weeks of Aug fishing the famous Thompson River each year. Stones & Hoppers (big ones) are the ticket. I tie mine on #4 Mustad Atlantic Salmon dry fly hooks.
