Before I'm jumped on this is not an anti Bl13 people post but an anti Bl13 post.
The concept is great, the fans are great but as has been said Bl13 is isolated. Away fans on one side, casuals and walk ups + a few ST holders on the other with the bulk of week in out, rain or shine ST holders at the other end of the arena. Yes the vibe spreads - but slowly.
The other issue I believe is using the whole block and the fact that it is behind high glass and nets. It bounces the sound off the glass and the nets dull the sound. So the vibe goes more round the arena than through/across it.
Ideally the people should be "moved" to say Blks 9 or 19 and we know what that means in terms of displacing high revenue seats and/or sponsors - so unlikely.
Going forward Blks 3 or 4 might be better but not the whole block (repeating the Bl13 glass problem). Instead maybe the top 3 rows of Blks 2, 3, 4 and 5 - or a something similar (more top rows in 3 & 4 would be better concentrated). Given the number of ST holders here I do not see this as a this season action but a plan for next season and that season's ticket marketing.
In the meantime keep using Bl13 and let the fans keep on belting out their combined support.
Oh, and has been said get well soon Sully. We need a DJ sensitive to the mood. We don't need music if the fans and driving the noise and support.
