As an example I can more easely get a crossing clearance through Birmingham IFR than if I ask for a VFR crossing. At least IFR i can be coordinated with other IFR traffic VFR i will either be told to remain clear or given a crossing only when traffic allows.
As you wish PACE. As I have said I don't agree with changing the flight rules just to get a better service than others, in my humble opinion.
I have no desire to get into a peeing competition on licences and ratings either. I do have a type rating or 2 or my own and can match you for hours.....
Take it or leave it.
