Sam Hillwrote a review of Black Diamond Compactor Backcountry Ski Pole on February 2, 2012
These poles are a great idea, have a few drawbacks for using as a splitboarder. First, when using the pole to flip up your climbing wire, the grip on the pole gets stuck behind the binding. Second, when chocking up on the pole, there is nothing to keep your hand from slipping down. Overall, the black diamond expedition is a little more robust and easier to use than the compactor. The only benefit of the compactor is that you can break it down to fit inside your pack.
