Thanks for the advice and offer there cloudhigh. I opened the same subject in the instructors section too (and forgot about this one. Sorry about that).
I guess the main thing for me now is to decide where to do the course. I've been told on several occasions now that you should do the C-Cat where you want to work as most school will take their own students over an unfamiliar new C-Cat. Knowing that we're going to be moving out of the area in the next 6-12 months I'm thinking I should wait until I know where we're going to be......
Cheers
