John,
That's a nice fly; pulled the pic from their site (looks like dyed deer or elk for the head/wing)
Very similar to Mike Lawson's Henry's Fork Salmonfly (I tied it with a dubbed and foam body)
as well as Bob Jacklin's Giant Salmon Fly
As big as all these flies are, a foam indicator tied in on the head would be a definite plus (guess my eyesight was better when I tied the Lawson and Jacklin flies). Looks like I'm going to miss out on the big bugs this year, so I'll have plenty of time to play around with ideas for 2020.
Regards,
Scott
