I think split boarders do well with other split boarders. When you get skiers and split boarders together, it can get a little tedious. Skiers have to wait for the boarder to de-skin and rejoin the board, which usually takes longer than a ski deskin. Then on the downhill, boarders sometimes have to choose a different line than the skier to keep speed. It can be a pain to regroup in low visibility or heavy trees, since the boarder wants to keep speed for the flats, etc. Rolling hills stop boarders dead and it can get very frustrating for them. I have nothing against splitboarding, but it can lead to problems. I really think skis are a better backcountry tool. A split board with edge-to-edge skins, however, is unstoppable on the uphill!
