Are Hexham depot running the 'Hexham' 10 boards today?

If so, would it not have been more cost effective for fuel economy & BSOG mileage to send out 3x of 6352-55?

I know the only pitfall due to the fluid allocation of Hexham & Riverside TVT B9TL's would be if a bus needed swapping out at the MetroCentre for any reason regardless of static boards.
