Definitely get over to the South face (far left on the map). The trails there are great in fresh snow. Upper Wild Thing is a personal favorite, and the glades over there (Stump Jumper and Loose Spruce I think) should be great in the expected conditions.
Also check out Jackson Gore (far right on the map), that whole part of the mountain was made for powder.
I'd agree with this. I personally like to park at Jackson Gore and head to Solitude to warm up. Nice easy cruisers to get loose there. Then head over to the south face for some fun.
