I'd have thought a cascade from London would generally be a bus heading into the second half of it's working life or with just a few more years left in it, as opposed to a five year old example. In years to come, it's entirely possible we could see Borismasters, as they'll be aging just like any other bus. With such a vast network in London, and new buses always on the cards, the older buses don't have much to do and it's why we find them elsewhere in the country. If there is work for them elsewhere in the Arriva fleet, they may as well be moved to take advantage of some free buses.
Also, when you've got a big organisation such as the Go-Ahead group, we have things like the OmniDekkas from Brighton & Hove going to Go North East, and their Citaro Artics migrating south.
