A letter - number - letter just doesn't work for me at all. I can handle letter - letter - number (i.e. RM1, RM2) but letters in general are just awful as route numbers. :p
Arriva's X3a must confuse you then :p Although I prefer Arriva's use of smallcase suffix letters on the timetables (shame they can't follow that onto the destination screens - not like they can't).
