Nice!! : ) Have fun my friend!!
For the ski question, turning with skis, with a windski is not a easy move as you could do with a windskate but it's fun. You could like a normal jibe or do like a air jibe, jumping they other side. This is not so hard. You could have some exemples on my windski videos such as this one! Have fun!
Before you ask how to built that.. ;)
