Even though I wasn't in this swap, these flies sure are terrific!

i'm interested in the hackle style of the fly in picture IMG_0062, where the hackle is all on top, similiar to a parachute, but where it has no post and the hackle is a mound on top of the fly. I saw it first described recently, but I can't recall where; it could have been in a magazine or online... can anyone help?

thanks for posting the pictures, rcream!
