I guess I don't see the problem with class E??? We use it here in the US and there isn't a problem with it other than freer access to the air.
I fly both IFR and VFR and choose to fly VFR when the weather is nice. The need for class A around major metro areas just isn't there. Class B offers the type of protection that you need and allows the flexibility to be more usefull when you have the time to offer that service...
