As a rookie Pitts pilot who just transitioned from a Super Decathlon I can back up Stik's comments.
1. Your first Pitts flight is like crack. There is no going back.
2. An awful lot of the Pitts' reputation on landing/ground handling is overblown. It's no Citabria but it's a very honest plane and does exactly what you tell it to do. My pre-takeoff checklist has an extra "head out of backside" check at the end and if you follow that golden rule you should be OK.
Get lots and lots of good spin training from somebody that really knows what they're doing.
