"the extra twin time wont make you stand out in a crowd of angry fATPL holders".......rubbish!
Multi Engine time will increase your chances of a job.
Here's my advice.......
Go the the US, do the CPL and IR (FAA) on multis - it will cost you about $30,000 - and will include your ME instructor cert and you can spend 6 months getting ME time for free.
Convert the lot to JAA - and then go and stand with the angry group of fATPL holders who have 800 hours single to your 800 hours of multi and see who stands out.
