Bill Shuck posted about this on the Flymph Forum and I thought it was an interesting pattern that makes a very cool fly! See Bill’s thoughts below. – Paul
Bill said, “Came across the basic pattern for this in a video on Matt Grobert’s blog and then, after watching another version being tied by someone else, came up with the below for use as an eastern Isonychia (slate drake). The original Shakey Bealy was a pattern tied by Nick Nicklas, late of Blue Ribbon Flies.”
