Hi Adam,
I trained at Stapleford many years ago, and now fly regularly from North Weald.
I believe that Stapleford is more orientated now to commercial pilot training although they still have a flying club.
North Weald has a good flying training organisation (two in fact) I suggest that you contact them all and visit to see what you think.
a trial lesson with each will help you decide, and the hours flown with each will count towards your ppl required hours.
