Well ... I live in Winter Park, so I don't have the ice to deal with like you, but I ski Steamboat as well, so here's what I'm running / planning to run this season. (FYI, I'm 5'9" and about 160lbs in the winter)
183 Volkl Gotama with Marker Duke bindings
177 Volkl Bridge with Look P14 (to replace my current 177 Karma)
175 Dynastar Phil Belanger Pro with Look p12 (it's a stiffer Trouble Maker)
Planning to add
171 Salomon 1080 Thruster
175 Salomon 1080 Gun (the old pocket rocket, before the redesign)
Both are just rock skis
And I'm thinking of gettng a more traditional carving ski, maybe a Volkl 12 foot TigerShark.
I have a pair of race stock SL skis, but those only come out for running gates, so they don't really count.
With this (and realistically, much less than this) quiver, I'm set for pretty much every condition ... I'm sure you'd modify it to narrower for the east coast, but for the western stuff, you'd be pretty set
Oh, BTW: If anyone is interested, I have a pair of 177 Volkl Karma's for sale and a 176 Volkl Gotama with Fritschi Freeride +'s and skins. Let me know if you want more info and pics
