I very much like the new network, all buses routed via the Travel Interchange, which will be excellent for connections, currently only 'more' (looks like a bus, runs like a disaster) operates the route, but soon we'll have a combined frequency of every 5 minutes with more and Transdev Yellow Buses, more run every 10 minutes, and from what I've heard the new service will run every 10 mins. So I presume it will switch between 4a and 4b, but we'll always need a 4.
