Allocations on the X20 are not doing verry well recently as most days the 2 max X20 branded geminis (7414/5) allways wind up on the 35 and/or X15 and the most common buses found on the X20 are 7445 4659 4653 & 4664 non of which are X20 branded and 1 of witch are not even max whilst 7414/5 are always on the 35 and/or the X15. To fix allocations Arriva should brand 4653 4659 & 4664 for the X20 and 7414/5 should have X20 sub brandings removed and keep shop work play brandings  as on 7413 then tge x20 will have branded viechles and the 35 and X15 can have 7414/5.
