Thanks to both of you for the response. I thought I had spent enough time sifting through this forum but had not come across the split shift concept.

If what I am told is correct I could be flying over in the sometime before the end of the year for an interview. This information and a great deal of other information I have read will be useful for me.

Perhaps I can buy you both a beer in thanks - if indeed the next stage does eventuate.

Kind Regards,
