Think part of the problem in the zone in the last couple of seasons is that it has been fragmented and unlike the early days the so called core members have been separated. Much easier to sound unified if those people were all together rather than spread all over the zone.To late to do much about it at this this stage i would think.
As much as some people hate it, if we started the game with Ring of Fire,its the type of tune that most in the crowd would be aware of and as much as its about improving the zone its also about engaging others in the stadium as well.Sadly that would require the stadium to shut the bloody music off before the start of the game.
Maybe it could also be about growing another zone in another part of the stadium.
