I'd get yourself in the Super Decathlon, VP prop is nothing to worry about - no aerobatic aircraft should be without one!
The Super D should have enough go with 180hp. I fly a Decathlon at Tatenhill - before the prop got changed for a fixed pitch item it was adequate with 150hp.
It took me 3.5hrs to get signed off for tailwheel - I'd try to finish the aeros course on the Decathlon, at least it shouldn't then take more than a couple of hours of dedicated circuit work to get signed off for the tailwheel.
Decathlon preferably over a Firefly, it's a lot more responsive, but
if you do go to Western Air, their Firefly's OK and Barry Dyke is a
good instructor.
