Pitts is GREAT when you can do aeros, but IMHO ist is much better to learn the basics in a machine that does not fly them as easily, so the Robin THEN the Pitts was the right way to do it.
As far as the inverted spin goes - one of my favourite manouvers displaying a Stampe was - half vertical roll, stall turn, flick on the way down. First time I tried this in the Pitts I decided to convert the half roll to a full one, did not get enough speed, or pull hard enough - flicked off the top with forward c.c., I suspect you can guess the rest!
