ItAs previously explained, it will be the PE. Which is a sick ski.
If you are looking for a good all mountain, with a few powder days, the extreme would be excellent. If you want more powder performance, and are a good skier, you might want to think about the kung fujas, it is 15 mm wider than the extreme, but will be that much more to deal with on groomers and such.
It all depends on what you want to ski, and how often you ski. If you don't ski that often (20 or less times a year) You will probably prefere the extreme.
