I am in a similar situation here in the US (private ticket,130TT) and I am doing aeros in a Decathalon, I am combining Basic aerobatics and a tailwheel signoff into one and should complete it all in about 12 hours. I have 6 hours aero/tailwheel at the moment and the improvement in my handling ability is very noticeable. Can't wait to get my hands on a the Pitts special or the Extra 300 that the flight school I'm doing it at has.
