We stand at the games and the only tickets available when I logged on to purchase at 9:30 were in the front half a dozen rows of the lower tier, so whilst, in theory, that would work, it didn't.
I can't see how only putting the lower tier up for sale first is a fair way of doing the front, middle, back split? Those who want to sit will be obstructed by those who stand due to them having to be forced to buy a ticket near the front?
