From my experiences of the 50 at least, I don't think anything bigger than single deckers is needed on the 50 most of the time, about the busiest I see the 50 is around the Washington area particularly Galleries - Lambton which is usually just short hoppers catching the first bus that turns up.

Not sure on the 1 myself as it's not a route I regularly see or use but I could imagine that one being busy at times, especially on a hot summer's day.

My thing with this though, I can't see Go North East wanting to upgrade any single decker routes to double deck operation unless they feel it's absolutely necessary and even then I think it could come at a cost of a frequency decrease, that's why I was always thought that the hybrids wouldn't go on the 27.
