Obviously the X9/X10 don't need a low height spares so could be covered by 6377 or a B9TL if required.
Will be interesting to see how they perform? Arriva's classic E400s have coped fine until 5 year old on the X18 but obviously due replacement now. 5 year in service on the X9/X10 is more than acceptable.
