The problem is Tom, that SVFR tends to bite me on the arse. Surely Booker and a taxi would be better. Don't forget that you can get a radar service from Farnborough LARS now;)
Personally I prefer to stay clear of fall that SVFR and LARS stuff. I like looking out the window to make sure I don't bang in to something going the other way.
I know one guy who would take great delight in calling for a MATZ clearance. If they refused He would just reply "Rodger. Climbing to 3,100ft to remain clear of your zone. Changing Frequency to London Information on NNN.nnn. Good day Sir!". Quite often London would ask him to transfer back to the MATZ for a clearance which he would get. The last thing they want is some little maggot with no Squark or no Mode Charlie crawling over their patch.
