Disregard what I mentioned about the Red Kites on ANE's main thread. But, if the Angel was to get an upgrade this year lets say to Streetdecks or B5TLs, do you think that 6118-21 could end up also being replaced with either newer single deckers / double deckers?

Not saying that they're old by any means but looking at the spec of them compared to the Streetlites plus the fact that the Angel is more of a hop on / hop off route, do you think they'd make suitable spares for the Angel (3x) and Castles Express (1x) if they were fitted with NSA's? The only thing that they would miss would be plug sockets.
