Ive hit rails and rode switch on shitty directionals, its not impossible but its really hard.
If you plan on getting into rails and jumps and become part of the freestyle scene I would advise purchasing twin tips. Try going into "Gear Talk" and post a thread saying..
"Hello, I am new to the freestyle scene and I am looking for some twin tip skis. I am (height), I weigh about (weight), I plan on skiing (rails, jumps, backcountry), and I live (location)."
there will be plenty of people who will be more than happy to help you out and choose a good ski for your preferred style.
All these kids in these here bright colors look like a bunch of skittles on the mountain today. P. Rod.
