SATCO,
I could add a few exceptions myself, the Slingsby, for one, is a lovely aircraft but there are few of the types you mention which are available to the private pilot.
Cosworth,
Just to add, there is no requirement for an AOPA aeros certificate. If your intentions are the more exotic types you mention then you would be better served going to one of the aeros training folk who train to competition standards, even if competition is not your goal.
A competition licence is worth more than the AOPA certificate.
