The club is more than capable of finding someone to work out the right way to approach this, even if part of the solution is to make clear what they want from the area in terms of atmosphere. It should be clear as day that it's an area where people are expected to sing.
We should also learn from the mistakes of SSL3. Yes it's one of the best areas in the stadium for atmosphere, but it could and should have been so much better.
If they strategically think this through and the right people are attracted into optimal areas for noise creation that will travel out to other areas of the ground, it will be a start.
Some might be will be happy to accept a continuation of the mediocre atmosphere that we have now, or even a marginal improvement, but this is the last chance, so it's reasonable to set a high bar in terms of what we expect from this.
