First and above all, though: polish up your French. Doing no radio at all might well be less bad than trying in English! Besides you'll need some French to have any success, later, with the restaurant waitress.
I won't be flying solo so not worried about the RT - just having an instructor who can speak English would be nice to discuss things with him. And my wife wouldn't be happy if I used my French on the restaurant waitress! Thanks for your reply.
