Twin Tip Skis!
Twin tip skis are slightly different than regular alpine skis. Twin tips skis are a great all mountain ski and designed to ski in either direction, forward or backwards. Twin tip skis are fun to use on all terrains but can give you an advantage over skiers not using a twin tip skis in terrain parks and half pipes.
If you enjoy skiing moguls, then consider a twin tip ski. Twin tip skis perform well in moguls due to the turned up tails.
