I think Chris Brooks has got a very nice set up in Gloucester. This is my personal opinion, but I believe he is passionate about providing the best training for the students, and not just making a profit.
Westflight not only provide CPL/IR training, but a structured hour building syllabus prior to commencing the CPL training which makes you a better pilot before the CPL training and hence improves your chance of those coveted first time passes.
I don't work for Chris, but I know Westflight by association, and I work at Glos as a PPL instructor.
