If you're not super tall, learn to fly in whatever is cheapest for you. The most important thing when learning to fly is your instructor. You have to be comfortable with him/her and they have to be good.
Have you any friends who have learnt to fly from any of the schools you are looking at?
These days flying is all about cost, something as marginal as £20 p/h can build up to almost £1,000 over the duration of the course. Thats why the right instructor is key, the better they are the quicker you learn and the greater chance you have of completing the course on minimum hours.
Finally, the most important advice I can give you and any other potential aviators:
DO NOT PAY UP FRONT FOR ANY PILOT TRAINING! PAY AS YOU GO!
Good luck, S88
