I've done the high route both nobo and sobo-

nobo I dropped directly into the West-facing gully that Skurka traverses into by heading due west from Wind River peak, and then traversed over to the next gully to the South as Skurka suggests because the first one cliffs out. Getting in involved a bit of class 4 downclimbing on good rock, and then it's a bunch of scree skiing all the way down- fast enough. Probably took me 45 minutes, though I do have a fair bit of experience in terrain like that.

Going sobo, the climb out was horrendous. I started up the north facing gully that OP took but it was a lot of very loose fist-sized rocks. P Probably fun to go down, but awful to try and go up. Since I didn't know whether the gully was good I traversed back onto the original route around 11700'. The scree was also terrible, so I took a rocky rib up to the top of the gully that was chill 4th class. From here I followed Skurka's route. I found the loose talus/boulders to be really frustrating to downright scary, like every ~5 steps or so a very large rock would shift/wobble under me, and I dislodged one rock about as big as me. It's probably better going down than up, but I didn't like going this way.
