65,000 and close to the pitch but no bowl? Something has to give there unless you have steep stands, deep stands or multiple tiers.
Each to their own, like, but I find multiple tiers are more visually appealing. That single tier stand at Tottenham's new ground looks out of place to me. Done right, I think multiple tiers help add intimacy to a ground and I personally think they're more overawing.
Single tiers are great when you've got orchestrated displays, when the whole stand is clad in the team's colours, when everyone's holding up flags or banners... I wouldn't want to be at the back of that tier though, I'd feel miles from the pitch.
