I think the Volvo Olympian was the last suitable bus to cope with the X9 / X10 mainly because it had a proper engine in it.
One decker that hasn't been mentioned is the Optare MetroDecker, and from travelling on it on the X1 when it was on there, it seemed quite happy to sit at 62mph on the Washington Highway.
