AF07, what do you teach aerobatics in? I remember doing spins and spiral dives in a Tomahawk when I was learning over the sea off Guernsey at 8,000 feet, it was fun. I wanted to go down that route, but with work etc I really do not fly a lot now, most of my hours were accumulated in the first few years after I got my PPL which appears to be fairly typical of PPL's.
