This one and another I caught last month, had a tendency to rock from side to side when standing - like the tilt mechanism was constantly firing off. I also noticed that, on the stretch between Station Town and the Trimdons, I had to look up and out of the window, or else I felt a bit woozy with being swayed about - big'un was sat at the front but said after we got off that he felt a bit queasy there, too. It was impressive on the A66 stretch approaching Middlesbrough, though. We were overtaking everything, uphill (In stark contrast to the X12 Gemini we got home again).
Yeah, pretty common of the Scanias to rock back and forth when stationary. Some of Go North East's L94s do it too.
I think Go North East's OmniCitys are geared towards being a bit more fuel-efficient and as such don't appear to be as powerful, but some of Arriva's are great once they get going. The late 4663 seemed to be one with an abundance of power on the 685, and 4659 (think that was the one at Jesmond before it moved to Ashington for the X15) was very much the same.
Still think that the OmniCitys are the best performers on the X93 to date - shame they don't have enough seats during the summer months! Volvo B9 is probably the next best thing, though.
