Hi,
I've owned and operated a 2004 Super Decathlon now for four years and I have to say it does everything it says plus more. Its rugged and very aerobatic. A slightly less nimble although useable machine might be the Citabria High Country Explorer (7GCBC) It has a Vantage IO-360 (180hp) which is certified for mogas and is a plus 5 minus 2 machine. It's just had an increase in useful load too.
PM me if you need more info. Good luck.
