There really is nothing like aerobatics. I HATE roller coasters with a passion but aerobatics are an absolute joy. That little adrenaline rush and the unstoppable giggling at the end just makes it. Seriously, if you're thinking about it already, just do it. There's a surprising level of control you feel because you're so far away from any physical objects - it's just you and the vast expanse of sky as your playground. It's been two years but I think I'm getting the bug again :P
