Can't help you on the location issue but I can vouch that the Super D is a great airplane to get your tailwheel conversion on. It's what I got mine on when Sherwood Flying Club had one up at Tollerton/Nottingham. It was a nice gentle airplane, has a wobbly prop so that was a new thing for me, and flew at airspeeds I could cope with. I really enjoyed my time in that airplane. My only prior flying was my PPL in 152s.
Good luck, anyway!
