Sorry Radar, but I'm with gregbell on Belgium. I've been 6 times this year routing from Koksijde towards Luxembourg, requesting a transit through Brussels Class B each time and I have had the grand total of 1 transit and that was only because I complained that their instructions would have me descending into the low level haze/fog. I'd go further and add that they have a tendency to "clear" you through uncontrolled airspace and the service from Brussels Info ranges from very good to downright dangerous. Charleroi and Ostend on thee other hand are very helpful.
