Bose, Julian
I'm prepared to defer to your knowledge although it does conflict with the views of the US instructors that I've discussed this with (however it is seems to be an area that causes some confusion with many people).
Whilst it is an academic question for me it would be sensible to pin down the precise legalities of this, which I am happy to accept mean that the UK licence restrictions apply.
For me personally, the view of Orlando from the air at night is insufficient reward for the additional risks involved, but that is purely my preference.
