ATP's in ABZ with BWA:
Despite all the flak, and depending on whether you already have any commercial experience, the ATP is a good 'craft in which to learn your trade (not bad fun too really).
Exactly the same applies to the ABZ-SCS route. Having said that it will get pretty boring after a while since this is basically the only route you will ever fly.
However, personally, (wait for the return fire), I think ABZ is a cold, dark hole more suited to population by bears. If you, like me, are a Londoner and haven't been to ABZ don't expect to like it much.
Hope this helps a little!
