BigGrecian, good points - speaking as someone about to do their CPL and ME/IR, how is that different to doing a SE CPL and then ME/IR? Surely that's 6 hours MEP training and then the joys of the IR, which if stories are to be believed is tougher than the CPL?
Is it just that 50-55 hours of flying on the IR gets you familiar with flying ME whereas 25 hours on the CPL doesn't?
I have a feeling I'm asking the bloody obvious!
