Here is the Adam's variant of the Flymph.
Hook: This is tied on to a #6 hook (which after halfway through the fly I realized I had nothing close to a #6 sized hackle....)
Tail: Brown and grizzley saddle hackle fibers
Rib: Optional. You can use thread, wire, or in this case, a couple strands of Krystal Flash.
Body: Adam's Grey dubbing
Hackle: Brown and Grizzley saddle hackle
