I think the 'sedgehog' is a broad church. I've tied and caught on Davy McPhail's Sedhehog Bumble (though I got the one pictured in a swap), which is really a classic wet fly given the deer hair treatment.
Top dropper pulled through a wave worked for me.
I tie a dry sedge pattern I call
The Egg Hog on Grip 11011BL hooks, Tiemco 103BLs or Fly Tying Boutiques's 103BLs. I usually fish it static but it has picked up a few when twitched in the surface. My most succesful dry fly last season.
Both can be considered Sedgehogs but there's a world of difference between them. Just the bunches of deer hair tied in in common.
