@ happy: I’m afraid you’ve got the wrong idea about aerobatics. This is not Frecce Tri Colore only. Aerobatics is done in gliders as well. And that is not really Formula 1 in aviation, is it? Aerobatics is something different to so called normal flying. And I think you should go for it. On whatever plane. Try it on a Blanik glider. Its hard enough. To do aerobatics you don’t need a Extra 300 on the first place.
Well as long as we're comparing: An Extra would be like a Formula 1 car and probably not the best to start with.
How about some loops and rolls in a Decathlon or something to start off easy...
...and then you can work your way into the BO105 slowly but surely.... 
Mates, it's highly possible that I've a wrong idea: all could depend from the fact that the only time I went with a pilot who was doing it, I just had 1 hr logged and still could not “understand” flight, so the pilot – in my mind – was a………wizard. Then when I asked the people in the school where I did my PPL, they immediately said “gorgeous idea to do an aerobatic extension, gives you more familiarity with the aircraft”, and I thought it was just pure……marketing. And 3rd when I told my parents (with whom I still live, considered that I finished the studies one month ago) about the desire of doing it, they went crazy mad, saying it was out of discussion til “…….forever or maybe ten years, when you will have enough skills!”, because it is highly dangerous. At the end, you all confirm me this, my point of view got lost, blurred. On my side I just remember that the day I was inside the cockpit, while the pilot was doing it, I never felt so free (like being part of a world you’re not supposed to belong to…..I do not know if anyone among you ever tried scuba diving, but one think is being just underwater breathing, another thing is swimming with mantas and turtles…but the idea is this one, more or less) and never had so much fun. At the end I did not know anymore who was right……..and if I was just being stubborn and careless as my parents thought….
