Why not level 2 ? That would be under the roof like the south stand ? If so it would be perfect for the noise to carry around the stadium
I would assume the club will make part of NSL2 corporate like SSL2 is.($adly) Isn't the plan to make L2 pretty much corporate and expensive seating?
A perfect scenario would be for the club to bite the bullet by improving the atmosphere first, install safe standing on NSL2, make the 2 central blocks on NSL2 official singing sections, and fill the other blocks on NSL2 with fans who want to stand and will join in singing.
1. Retain NSL1 as it is.
2. Retain NSL2 as it is and make the 2 central blocks the new singing sections where flags and 2 sticks can be waved, held up, and banners can be hung.
3. Build a stepped up NSL3 from NSL2 in the same stand, which would hold X thousands City fans.
The kids could stay in NSL1. Problem solved.
The new singing section/s would be in a prominent place on NSL2 so the whole stadium could see it and hear it including the away fans.
The home end would be complete with a large terrace of home fans on NSL3.(same terrace as NSL3, but stepped up)
To do this the club would have to sacrifice a new corporate area (I don't think the current corporate boxes will be retained in the expansion)
