Thwack,
My thoughts too...I'm thinking the ostrich herl isn't even necessary.
At any rate I like that fly..going to tie some...
I'll admit I'm a Denny Rickards fan and it looks very much like his Stillwater nymph...could be good with a bead too...
Those after-shaft... or whatever in the heck they're called.... have always intrigued me because they are rather delicate and should impart motion to the right size flies.
