Thanks for those tips - btw stiknruda, it was the pre-PPL flight in your S2 that started the ambition so you're to blame for the ensuing expenses
I've checked out Budd Davison's website and a week or so in Arizona may be the best way when I have some tailwheel time. I also like the idea of a whole week's Pitts-immersion!
I don't want advanced aero, just need to get to the stage when I can confidently get in a single seat S-1 knowing I can get it (and me) down in one piece reliably in different conditions at a variety of strips.
