Maybe something like an OM936 streetdeck may be good for the TVT would prove good, 6377 from what I've observed is incredibly reliable and verry much capable of operating challenging routes. Also when we're on the topic of reliability as much as I like them the interdecks on the X9/10 seem to be a nightmare for reliability, they seem to constantly brakedown and there's never all 7 out I'm a day, often a levante or regular bus (mainly a B9 or 6377) stepping in for them, since February they've seemed to have more brakedowns than the B5s did and the levantes when they had afew months on. Maybe since 7148 is at Riverside they should trial thst on the X9/X10 against the elites and older levantes.
