I'd also point out that, compared to the previous pattern of the X21/22 interworking, the vehicles on there now either get 15 mins sit at Ashington each trip (on an X22) or a breather on a 35 between each X21. There's also no A189 blast on the X21 anymore.

I'd not read too much into the allocation of Pulsars/Streetlites, they're seen as single decks and allocated as such. That said, my understanding is that the Pulsar is viewed as a more capable vehicle, and the allocation of the Kelso X16s backs that up.
