I was looking at it from a cost and marketability viewpoint.
Assuming that the CPL holder had to pay for everything, which seems par for the course in Europe and what you have to plan for, it seemed that 1/2 a MPL(A) course might be cheaper than an indpendant IR, MCC & Type Rating, plus if the MPL was 'sponsored' then you might be better placed to get a job.
Accepting that this may fix you in the RH seat for some considerable time may not be an issue.
