Aerobatic freeware recommendations anyone?

Hello,
My wife bought me a aerobatic demo flight for christmas and it was fantastic.
8-) Now I want to learn how to fly like that in FS9. My demo was in a Citabria. I would like to fid a good freeware one if possible or find another type of plane suitable for this type of flying. The default Extra is nice but alittle on the sensitive side. Anybody have any suggestions?
Thanks for any input
