Biggus, I don't regard the '05 as the villain and I retain my sympathy for those who made an informed decision to transfer in 2006 from the older scheme.
To gain protection under the '10 year' rights and individual would have to have been over 39 years old when the OTT happened in 2006 (it was only open in 2005 for new entrants). For those who made a decision to transfer to '05 post their IPP this has become quite a key point.
Whilst the new scheme is not expected to come into force until 2016 the 10 year point is an arbitrary line drawn at age 45 on 1 Apr 12 - in other words it will provide protection for those aged 49 or over in 2016 when the scheme is predicted to go live. Or as one wag has pointed out the 'protection' will insulate all bar 2 air ranking officers from the change.
