As for doing it on a Cub instead of a Super Cub, good idea. Flying doctors should prescribe 30 minutes of Cub flying, door open, on a summer evening as a panacea for all ills. Bourn is a pleasant place, (although its non flying facilities are very basic) and Lindsay is a nice bloke. Only slight drawback perhaps is that the runways are hard (knobbly ex WW2 asphalt). Cubs like grass better. One further suggestion, therefore: Mike Derrett, who teaches on the Moths at Cambridge but also on the Cub at Andrewsfield, which is a pleasant grass strip in a pretty part of Essex.
