slim, we'll probably have to agree to disagree over the size of the London Zone but if the thrust of the argument is that people are infringing it because one thinks it is too big, that's not really a particularly valid argument for making it smaller.
London LARS is coming soon(ish), so a better radar service is on the way and if the Zone ever gets reclassified, which is quite possible, to C then it's also easier access for the light aircraft as well.
Enjoy your hols.
