Go about it comparing the two, and like you said showing what skiers can do now days. Some would argue that skiers are going even bigger in the halfpipe. Mention also how skiers can now drop "true switch", and the amplitude of dudes like Dumont and Tanner. Also mention skiing halfpipe being featured as a majoj event in the X-games which has highly influenced the Olympics now.
Good luck..its a good topic!
