Hi MAX
I back up 100% what they guys have said, with one exception. Going through training/conversion there were many roster changes, some to your advantage. If it meant the difference between somehow being non-compliant or cutting your 4-month stay away from home in the Biosphere, sorry, Headland Hotel by a week, for the sake of your sanity go for the latter. This business of getting one trip home if your course is more than 30 days should read once every 30 days. There's only so much Wan Chai you can take.
