Sounds like you're looking for something similiar to what I'm looking

aerobatic, but have the structural strength and are designed for that
"fighter jet" type feel. Anyway just some food for thought.

I looked into the pulsar and sting quite a bit and although the planes
look pretty nice, I'm not quite sure the companies have their act
together
