I agree Tonker.
The chaps at London Met used to advise us to do it on something simple, like a twin prop that you are already familier with, rather than a jet as you will waste alot of time just learning where things are and how systems work, which is not really the point of an MCC course.
An MCC is to teach you how to operate in a multi-crew environment, rather than handle a jet - thats what a type rating is for.
