Ludwig,
As a humble Pitts pilot, I'd like to endorse c'Wally's caveat.
Perhaps you'll be able to find some bright, young, brave thing who'll gently wring you out in a Cessna Aerobat in your neck of the woods.
Wring, neck, woods - oops sorry that'd be next weekend!
Seriously, don't think that you've much to worry about, it'll all be okay IF you have the right instructor. You are doing this at La Porte, ain't ya bubba?
