Nick,
It is important to remember that persons offering you advice on a forum such as this are anonymous and may be totally unqualified to offer such advice. Some of it seems very good but how can you distinguish the genuine from the mischievous or just plain daft? Even people describing their own experience may be serving some agenda other than your best interest. It is not unknown for FR management to contribute to these forums with the express intent of misleading pilots. I suggest that you contact your union for advice. At the very least, they can warn you if any of the accountants stipulated by Brookfield are in any way unsavoury.
