Replying to Have 2 pow skis, only one pair of bindings. Which skis?

I Have a pair of Surface New Life 194 and a pair of K2 Obsethed 189. Both are Last years models.

Only One pair of salomon sth 14 drivers. Which ski should i mount them to?

I live in Beaver Creek, I will be skiing @ Vail, The Beav, Breck, A Basin, and in Lake tahoe for Xmas. At least 100 days this year in Colorado.

These skis are totally different. I have no idea which one i would get better use out of?

The only thing i can concur is if there is less snow use the obsetheds, if more snow use the new lifes?
