I say get two skis. Any ski in back-country or pow should be 110+ underfoot. But we've all been there. You can only own one ski. Here are some recommendations.

Skis on this list I'd seriously consider If I was in your situation. The K2, Rossi, ON3P, Kastle.
Out of all them the most curious is the Kastle. They make dope skis. This year they made some twin tips in three categories pow,all mnt, park. I wanna test them out.
This is just a short list of what might work. Check out all the others listed on the thread as well.
