Luton base.
Flying camel. I have been based LTN, EMA, LGW and back to LTN and while EMA was the best LTN is a good compromise between a varied route structure and being small enough to get to know people. It does have the added bonus that if you need to resolve an issue you can walk upstairs and see someone. Just watch out for a long commute, it's not sustainable long term.
Good luck
