Wow, just logged back in to see so many super helpful detailed responses, thanks everyone
I need to digest what everyone has said so far so will respond in more detail a little later.
Really appreciate the recommendation and offers, will definitely consider all.
I live in West London (about 10 mins from Northolt airport, which I am sure many of you will know!)
BTW - my nickname has no meaning whatsoever, just tried to think of something aviation related. On reflection, "HighGlider" may have been the better choice!
