I have to disagree here, the X21 isn't a flagship route (profit wise) unlike the X9/X10. it just got new buses as the old ones we're knackered. It definitely doesn't deserve new buses again, the fact is can't hold a night service shows that it isn't one of the most profitable services. Plus the X9/X10 is a totally different route to the X21 and they're only getting replacements as they're wrecked from putting a city bus up and down a 70mph road all day. The X30/31/45/46/47 deserve new buses for once and are arguably more important routes than the X21 which have always generally had new buses on especially the Red Kite's but are getting on a bit now.

Personally I'd rather see newer buses on routes which go into city centre's with stop / start technology etc, where pollution really makes a difference and harms people health rather than something in the middle of nowhere.
