I've got a little time in one...amazing airplane. The side stick is completely natural, I liked it a lot more than the conventional setup. The thing has some serious get up and go too. If your used to 172s and Warriors it takes some adjusting to, initially it's a little heavier work load in order to stay ahead of the airplane. After you get used to it there should be no problem, though.
I don't have a whole lot of time in one so that's about all the insight I can give ya. I know some other people around here have a considerable amount of time in them, that should be able to help ya out more.
