Replying to Center mounted park skis in the mountains?

The university where I go to school is offering a bunch of different ski trips to BC. Because I am a student and have to save money wherever I can, and I'm trying to spend as little as possible so I don't want to rent. I only have dedicated park skis, as I come for the interior of Canada. I was wondering if my LINE TC's would work alright in the backcountry, or if they would be constantly sinking and a pain in the ass. They are a wider park ski, but I'm still worried about flotation when all of the weight is in the center of the ski. Also, I won't be shredding expert lines, just some nice deep pow. Thanks for helpful responses.
