I kept coming back to that one but Balshaw Lane to me isn't really a suffix, it's a descriptor. A suffix (ignoring the strict dictionary definition of one which is for example -d on close to get closed or -ly on eager for eagerly) would be a compass point, central, town etc and just a single word. However reading the wiki entry for EBA I can see that Balshaw Lane was added for the reason given in clue 5, so I'd go with it, I just got a little too hung up on what constitutes a suffix, after all, it's a game we're playing.
