Fascinating to hear of your experiences. Thanks for sharing.
One reason I chose Bristol & Wessex was because I'd be learning in controlled airspace (class D) and jumping in the deep end as far as the radio is concerned.
I've paid for everything up front too(!), which I know is extremely risky and controversial, but B&W are a sound establishment and I've paid via the credit card so I'm none too concerned. If I was learning over the space of a several months or more, however, I wouldn't have considered it. Do not try this at home!
