I'm a competent skier, and a competent snowboarder. We're heading out west, and I am planning to take my east-coast skis, and then if we get a good snow (4+ inches?) rent some wider skis. But, I've had no experience skiing powder, but find snowboarding in powder very easy and enjoyable. In the long term, I'd like to be able to ski in powder, but I'm not sure that I wouldn't rather bring along the snowboard this time in case it dumps so I can get out and enjoy it without too much trouble.
So what do I do: bring skis and a board and enjoy all possible conditions today, putting off learning to ski in "good" snow? Or rent some powder skis should I have the opportunity this trip, possibly enjoying this specific trip less but setting the stage for the future?
