Replying to K2 PE's, 179 what should be mounted and where?

Hey everybody,

My brother wants to buy some PE's (08) soon, the only problem is that he doesn't know what bindings he should mount on them and where he should mount them. I didn't knew it either so maybe you guys could help...

This is the first pair of twintips he's going to use, he will use them for groomers as well park. He has 15 weeks of normal skiing-experience, but he wants to try a bit more freestyle stuff.

So, where should he mount his bindings and what bindings should he use?

Thanks in advance!
