From a route point of view, both are pretty similar to Slatyford (believe where your based).

Just urban/suburban routes where you do 10 mph for most of the route going around every housing estate, X1 aside on the short express section from Springwell to Shiney Row. 

The 340/341 and Washington Locals by far the worst for it.

The 3 Arriva depots are the depots which have the best variety but understand there's a commute involved. Blyth included because of it's interworking so you'll end up everywhere every day.
