the Face at Mt. Hood Meadows which is about a 40 degree slope on solid ice that is clear blue after freezing rain
Only after a freezing rain? Lucky bastard. Seems like I see blue ice every day after 3pm around here
I would tend to stick with boards that are a bit stiff with good dampening of vibration. One of the most annoying things about ice is the rough ride.
Seeing as how you're already on a Ride board, you might want to try the Concept TMS, the '08 replacement for the Timeless series. The dampening on the Timeless is top notch, I don't even feel rock hard corderoy under mine, but it's still a stiff board with lots of pop. A long effective edge will help hold you onto the hill, but as Snowolf said: if your edges aren't sharp it really doesn't matter what board is between you and the ice.
