YEEHAAA!
Aeros - I have done a bit with the ATC as well and off course became aeros mad (straight and level was just not intersting enough!)
During my PPL course...i had to kill a fair few hours as i completed the syllabus quite quickly due to a lot of prior training yadda yadda yah... so went up with my instructor and did AEROS!
I have also been up in an Extra 300 a few times which really taught me about aeros - although you have to realise that when you hop back in your normal a/c its roll rate and response isn't quite the same; but it was still a fantastic experience.
A lot of clubs also have an aeros policy - i.e. you have to be checked out by a suitable instructor and do solo aeros (scare yourself!) before you do aeros + PAX.
Anyone doing aeros is dangerous - anything can go wrong and i guess thats the thrill factor in flying.
Having a PPL is a bit like driving - you've got the license, now the learning really begins
Have fun!
