Replying to Pow-pow ski gear - advice on gear + sizing

Hey everyone,
first post so appreciate any help.

I'm in the market for some new ski gear.  Was a skiier, then a boarder, now i'm going back for some pow-pow sticks in my quiver.

I'm set on Marker Baron bindings and Supercharger Sparks for boots (have wide feet and nothing else fits), but I'm having trouble deciding on the right ski for me.

FYI  I'm 5'6", 155lbs... level 8 skiier or so....

I live in Calgary, so am skiing interior Rockies and spend most of my time in the open bowls/glades (50/50 split)... So I want a mid-fat pow machine, that can do 70/30 off/on piste.

I've had many suggested to me:  Line Elizabeths, Volkl Gotama's, Atomic Snoop Daddy's and I've demoed the 166 Czar's.

Any other suggestions?

In terms of sizing, I've also been told to go 170-175, but I dunno if this is too long.  I am going with twin-tipped so I guess it skis short...

anyways, let me know any info you got.  I'm gonna rent some skiis this weekend to try out a longer length, and am hoping to make up my mind and 'order' by monday or so....

thanks!
