Uh, me, I think. The above sentence is a triple-negative, after all.
Ian Moutter, who defintely has the street cred in England that Borger has here, argues that the parachute is more a true sub-imago than is the catskill. Moutter points out that a Catskill's hackle collar will push the bundled tail into the water where it represents the shuck of an emerging dun.
Because I believe the parachute represents a true adult, I am not a fan of tying off on the post. I tie the collar concave side down, and I don't want the hackle pushed up. Further, I have found (YMMV) that a tie-off on the the post is more likely to come apart than a tie off, behind the hook-eye.
One of my favorite patterns is a wonder-wing parachute. No way the split wonder wings imitate the body of a hatching bug.
