"He'll often be on the Yellowstone River using a size #6 or perhaps a #8 bead head fly, hooking and landing some impressive sized trout, including a 28" brown a couple years ago."

John,

I am interested in knowing more about the flies your friend uses. Are they just a softhackle fly tied much larger? Do they have a tail? Instead of calling them a softhackle fly, would it be more accurate to call them "flymphs"? Any information you can provide would be appreciated. Thank you....
