I'm not sure they've been dumped on services that don't really need them? The conversion of service 16 from single-deck to double-deck allowed the withdrawal of the scholars 816 service (which has always historically duplicated the 16), allowing a cost saving to be made.

It's also permitting the cascade of 4x Euro 6 double-deck buses to services which need to be Euro 6 (i.e. one board on services 26/50 due to capacity issues on one journey on the latter service, and one board on service 25) and/or provide a more adequate number of spare buses which are Euro 6 and of a high quality for customers.

Agreed - given that 6064 has barely been in service for more than a few weeks, and has been back at East Yorkshire since 1 October for further modifications, I wouldn't have expected any others to be converted this soon.

Get the first one right, doing the job it needs to do, then yes, going forward, they'll likely be converted on failure of the Hybrid unit and/or other major components.
