KMS,
Missed you over the weekend
No first hand training experiences, but have recently had to fly with a recent CPL and a recent FI trained by the Yorkshire source you mention.
Would be fair to say that I'd consider very carefully before going there.
Copter 2424 I have no links with the Yorkshire training provider mentioned but if you are considering them I'm more than willing to ask the two guys I've trained recently to PM you detailing their thoughts and first hand experiences.
Find a school and an Instructor you like. Visit a few. Check pass rates and ask to speak with any recent students. I've found that whilst you definately get what you pay for, sadly there are times you pay and don't get all you should. Past students are a good source but try and keep you're q's purely factual and accept that there will be possibly some personality clashes.
Would echo, try not to work for free, it helps none of us.
FI course will teach you more about your own flying than anything else. Enjoy
