To be honest, with the exception of the 308, I don't see either the Streetdeck or Volvo B5TL Gemini 3 fitting into any doubledeck route for Arriva North East whatsoever. I think Arriva should stick with ADL bodywork for all bus types and if they see the benefits of using a heavyweight type on the X93, the Scania Chassis on the E400 MMC would be ideal for the Ashington Express work and the X10 / X11 from Blyth but, as Arriva like it, they put fuel economy before reliability and punctuality. If they cared about them two, they would've ordered B9TLs or N230s when they were on the market rather than E400s and DB300s
