Did my CPL/IR at Leeds flying school in 2005. Excellent helpful bunch of chaps. Got some positioning flights for practice and, yes, the sim was available for practice too, free of charge, which is a huge help for the IR. The instructor with the blue BMW was a bit of a chump but every place has one. As to the weather, yes, Leeds is some 600 feet up perched on a hill, but I don't think I had too many more problems with weather than anywhere else. ATC were most accommodating so circuits weren't an issue. Yes LFS HQ is a mobile office, it's quite big, has a kitchen, loo, classrooms, internet access, what else do you need?
Renewed my IR with Multiflight last winter, simply because it can be done in their sim. It was a thoroughly painless process with an hour's excellent instruction followed by a straightforward test.
I'd recommend either establishment, but what attracted me to LFS was the reasonable cost of the course for a lot of hours in the aircraft. The Cougar is a good aircraft, if I can pass in it, anybody can.
