Even if RAAus had the right aeroplane we are prohibited in using them for aerobatics/spinning so it's a moot point. As was said above, there are plenty of the right aircraft available and in my opinion pilots should experience spinning and recovery. As to different recovery techniques, well, as we can't spin ours it is difficult to tell, but most factory built aircraf have a technique for inadvertant spin recovery in the POH. I haven't spun an aircraft that doesn't recover using the P.A.R.E method. Also remember getting into a spin inadvertantly is going to be a very, very different situation to doing it deliberately.
