I find that it is a norms for SBST to deploy Volvo MK4 buses on
feeders / short haul route nowdays. Even ADDs are introduced
nowdays to such routes.
Rather, I find that services like 119, 232, 238, 265 and 268 are
really the ones that are being pampered by SBST with those Scania
K230UBs. And even service 119 with Volvo B9TLs too 
I dont find K230UBs on feeders like 238 265 268 pampering since
its suppose to carry more loads.
