The Grand River Fly pattern by Ian Martin and presented by Rob O’Reilly has great possibilities for mayflies presented in the surface film or just below on a river or a stillwater. As O’Reilly suggests, vary the size and color for different mayflies. I like the possibilities of this pattern. Notice the straight shank hook and in this instance the straight eye.
Bob remarked: ‘I would probably burn up the whole fly while burning that tail.” Do the burning of the shuck fibers first. Then if you mess it up you have not wasted the tying effort.
