I have spent the summer building my skills with a GP Big Stick 60 (converted to tail dragger) and am now quite comfortable with it. I am beginning to narrow down my search for a next plane to purchase or build over the winter. I am looking for something that can introduce me to more advanced aerobatics (beyond basic loops and rolls) and general sport flying without getting too far beyond my skill level. I have considered the GP Extra 300, but am afraid that may be a bit much of a next step (thoughts on this?). I am currently thinking about the Chipmunk and the Sig SE. I would like to stay in a 60, but will do the SE at a 40 if that is the best plane. I can use the 75 engine later for a warbird.

Thanks for your input.
