Don't believe everything you read on here is my first point. Secondly I haven't been to bcft so CAN'T help you with that one but I finished at Stapleford in Feb and can't praise them enough and have yet to hear a bad word. With respect to too many students, again they are busy (a good sign) and managed very well by certain employees. The fleet is large enough to cope with all elements of your training and sims are fantastic.
Go with your gut feeling as everyone is different and only you know what feels right. I'm in no doubt that other happy Stapleford customers will back me up.
Good luck
