Bristol ATC
It sounds like the typical non NATS regional dilema. Package offered can't tempt anyone without any real experience and usually the self-improver ATCO simply can't hack it. Cardiff may work a fair bit of sky in that part of the world but they do nowhere near the amount of LARS and co-ordination that Bristol does, they simply seem to have a good contact in 'airspace allocation'. Bit of a jump from Filton to Lulsgate in traffic levels, not a good move....
