I've done Green Wilson and Friends (as well as a number of the 10th mtn ones). GW isn't bad; Friends is a slog: 11 miles and most of the elevation is gained at the end when you're spent. Once we got there I found the closest thing to sit on and sat motionless for 20 minutes, didn't even have the gumption to get my boots off. It's definitely the most spectacular views from any of the huts I've been. As with all Braun huts, you really need to know you're avy protocols, many aesthetic lines to die on.
Here's a TR that helped us out, unfortunately the photo links are gone:
