Gonzo,
the opposite happened to me. I did the APR course after Area 2, which gave me an advantage over the other students. As I hadn't done aerodrome for two years, when we were given the list of available units, I chose radar units, including Heathrow Approach.
However, after watching me on radar, the head of training at EGLL decided I would be a good candidate for Heathrow tower (He said I handled busy traffic well!) so they paid no attention to my choices, and sent me to LL.
After 2 years of radar, I wasn't quite up to speed on aerodrome, which put me behind the curve. (13 different mentors, all with different standards, didn't help!) I was the first to admit that Heathrow wasn't for me, and luckily I got out. NATS seems to insist on silly postings.
Proper selection could have saved a wasted year.

Ps, I was there while you were training!
Hi
Shame that happened, there was one other on our course who wanted LHR along with me. He got approach and failed to vailidate......if only those two postings had been reversed????
