Would it be reasonable to do Mt Whitney via the MR if I did Mt. Shasta via the Avalanche Gulch route and Mt. Adams through the South Trail? When I did Avalanche Gulch, I turned a bit to the left and went through this Chimney. It was pretty icy because there were around 70 mph gusts during that day. But when I check through google maps, I don't think the angle ever exceeded 40 deg. I don't know if the MR on Whitney gets that steep. On AG, I felt very safe and really wasn't that bad.

I know its mostly dependent on my own skill level and what I feel comfortable, but I thought if AG got any steeper, it really wouldn't be an issue for me. I just wanna know if its reasonable for someone who's done Shasta to comfortably do MR as well.
