Ken,
I understand your dilemma. I love my Extra 300L. I love flying aerobatics. But I have no compelling desire to compete (we can talk about the reasonswhy some other time).
I love teaching about aerobatics (stalls, spins, upset recoveries, etc.), giving aerobatic rides, introducing pilots to aerobatics, and just flinging myself around the sky (all that "...danced the skies on laughter-silvered wings;/Sunward I've climbed, and joined the tumbling mirth/Of sun-split clouds - and done a hundred things/You have not dreamed of - wheeled and soared and swung/High in the sunlit silence" stuff).
Therefore, I rarely find much of great interest in Sport Aerobatics.
If you're interested in future contributions, however, shoot me an email.
