I did answer Montana Life's questions. Not like me not to. Oh Oh Phil, Do you need to have your eyes checked? 😛

For now I've removed the EID field in destination table so I can continue with my goal of learning a few more transforms in 2010. Thanks everyone for advice on 2012 install, which I do need to tackle, but was for the purposes of the question a workaround. I read that 2012 isn't really bringing forward any new integrations services functionality, is rather a shell for 2010 anyway, so i would probably still face that strange issue.
