Both Morrison and Mt. Laurel are fun in the winter and you can't beat the approach.
This past winter I climbed Morrison twice; first by the NW Ridge and secondly by the Death Couloir. I found the NW Ridge to be straightforward and relatively free of any avy danger. Primarily the descent and approach were the most prone to avalanches. The Death Couloir was fantastic, but it won't be "in" in the time frame given.
I did Laurel quite a few times last winter and found it to be very enjoyable (thus the numerous times). I would say the NE Trough is the best route on the peak: long, a few interesting sections, and aesthetic. The NE Gully wasn't terribly exciting, kind of a slog. Either can avalanche though, so be careful and check conditions. I climbed the NE Gully after an avalanche cleaved off and ran from the top of the gully to the very bottom.
I would say to be smart, get avy gear, learn to use it, go with partners, and tell people where you are going. That being said, last winter I did all of the routes mentioned solo. I was just careful to check avy conditions and I turned around a couple times before finally completing the routes due to sketchy conditions.
