If you have considered EMA and Nottingham then perhaps you should look at Leicester too
Gamston too if you're at the north end of Nottingham. Air to Ground but a busy airfield with biz jets to choppers.
FWIW I trained for power in a full ATC environment. You get good on the radio with procedures and all the other guff but the first time I flew into a short strip I was bricking it, not because it was a short strip but because no one spoke to me when I called the a/g frequency!
It's the other way round with guys who learn to fly at a grass strip with a couple of movements a decade. They tend to avoid full ATC airfields and go round the edge of class D. This is a generalisation by the way, I know it doesn't apply to everyone.
