Totally agree with Redhill being a place to avoid. I've had several bad experiences there including being bo***kd by ATC on a CAA test. Fortunately ATC then went on to B*** every one else in the circuit. The examiners comment was that 'Its only a grass stip, not Gatwick'
I've never worked out what ATC at redhill provides. Go for A/G like Waltham.
