Leeds gets my vote. All facilities, weather not that bad really. All the airfield you goto have great facilities too. Humberside, Teeside and Blackpool. SID's are very straight forward and flying to Pole Hill to join the Airway is not a long slogg.
When chatting to Manchester to join the Airways they are very good and not majorly busy, so it's good to be able flow and not stuggle to get a word in.
The airfields you goto are open late so I managed to do some IR training at night, which was great fun, nice and smooth! good way to learn for harder conditions to come.
