I think it should be ST holders, not ETC. There are people who go away in Europe and hardly any of the mundane home games. It is quite important, as it could effect the nature of support the team gets at Old Trafford if we end up there.
I know we don't get many tickets, but if we get to Old Trafford what about half and half? Half the tickets to ETC holders and half to season-ticket holders. OK, some people will qualify twice, but there might be less moaning that way.
