In honor of John Scott, I would suggest adding rubber (or silicon, etc...) legs to the terrestrial version. Actually, it isn't necessarily a bad idea with the original. Instead of tying the original, Hans Weilenmann has a video of the improved F fly which should hold up better than the original pattern with its exposed thread body, which a peacock body should accomplish. He also had a suggestion for the wing. The video link is below.

P.S. Hans, please upload more videos!
