I'm not based in Brum but I know a little about their new links - they have two main links, a 4 day and a 5 day pattern.
4 day sign 170 & Voyager, Reading, Manchester, Bristol, Nottingham, Stansted, Cardiff, Tyseley and the rivers plus usual diversions.
5 day lose Leicester-Stansted but add Reading-Bournemouth and HSTs.
There is a feeder link system which new starters join so you won't learn all the routes at once but you'll pretty much get to choose which pattern you prefer and I get the impression progression is quick.
