If the away fans were moved we’d have an extra 1000+ City fans in SSL3. We’d have the whole of SSL3 full of City fans.
Just as importantly, we’d have an extra 1000+ safe standing seats that are already installed in the SSL3 away end, that City could push as a new singing section in SSL3.
We’d end up with the new 8000 capacity North stand home end, a 6000 capacity SSL3 with a 1000+ capacity singing section, and the SSL1 singing section.
Obviously we’d lose the singers in 111, 110, and 109 if City put the away fans there, but that would also lesson the effect of their vocal support. The away fans in blocks 111, 110, and 109 would still have access to the coach park, so that wouldn’t be an issue.
Unfortunately I don’t think it will happen as I think the club are happy with the current away fans set up.
