Yep. I also wouldn't really class GNE going for the same type of vehicles (i.e standard double deck buses) as a massive improvement, especially considering the improvements that Northern are promising within the next few years.
Just a query, do the tables brought in on the Streetdecks lower the capacity? That's one way that I could see GNE improving the TTX, however then the capacity issue comes up again.
The current B9's have a capacity of 73 seats compered to 68 for the Streetdecks with tables. The enviro 400 city had a capacity of 69 seats (also with 4 tables) so although there is a difference, it is quite small and may be worth adding tables for passenger growth.
