As an instructor on a totally different airfield I have no vested interest but can recommend White Waltham as a great club with both a flying school and lots of keen pilots/interesting a/c. Also a good choice of runways which will be important when flying circuits. Nothing against Wycombe but there is a lot of gliding activity and not much in the way of interesting a/c around. Either would be a lot more fun than denham which has two schools but no club.
