Changing your entire setup before leaving? That may be dicey. I'd say that being comfortable using your setup is part of the recipe for success, and you might not have enough time to test out some new pieces.
However, I understand that your gear may evolve over the trip, as you evolve, so you may be inclined to change things out after you've used them and desire something "more".
I made my own set of rigid CF poles (will post later), but I have yet to test them out. If those work well, I'm inclined to sell my Black Diamond Countour poles (not CF, 18oz).
