I would also agree and say go with the something extra. this plane has tought me so much as for aerobatics.
after my trainer, i made that decision to go for the warbirds instead of the aerobatic airplanes. I did that for a few years, but then wanted something more from flying.

since going into the aerobatics, I love it, don't know how I could ever do with out it. I would say, you need to make a choice if you want to go into the scale or the aerobatic section of flying. the aerobatic part will make you a good pilot, and really make you use that left hand more so then with the warbird part.
