All well and good having bigger buses on the X20 however one board does (or at least used to) work onto the 79A which has to be Solo allocated so therefore either this interworking would need to change (the other 79A is/was a 33) or would there be a mixed allocation?

One side note, as a driver I would prefer a Streetlite (especially one of the smaller ones which are rockets) over a Merc.

I could see the Solos going back on the X6/7. Passenger numbers on there however I found the 53mph limited speed on the A19 an issue.
