My post from the other thread.
If the coin chucking / spitting risk can be managed then I say away fans in East 3rd tier.
Away fans could have blocks of the 3rd tier starting at 309 then moving towards the north - easier to give teams with less fans a single block of about 250 seats in 309, or about 900 in 309 plus 308, or about 1,600 in 309/8/7. Keep adding a block until you get the right number needed.
When we have to allocate for a lot of away fans like the FA Cup then the whole 3rd tier could be allocated - about 5,500 seats.
You can put in a set or two or three of gates on the 3rd tier concourse to keep the segregation there. Close whichever set you need depending on the numbers.
Whatever isn't allocated to away fans could be city card / access card sale - would mean no season tickets in east 3rd tier. Could mean it's easier to sell out against the likes of Fulham where we end up with hundreds of empties in the south now. Cost of moving and putting new gates etc could be made up in no time from the extra sales.
Fans wanting to give the banter could be in South 211/212 and giving the abuse to them up in the 3rd tier.
We'd probably get all the South being the singing stand if we did this.
The other thing that crossed my mind was where do we like to be at our away games?
We get lots of posts along the lines of "it'll be great because we've got the whole end" like at Blackburn or Wigan. When we play at Newcastle we get the "stuck up in the gods" comments.
We are giving the away teams what we see as an advantage. We like having a big block of seats behind the goal when we play away. We could have the same at home by having all the south stand.
Make East 3rd tier for the away fans and we give them as little advantage as we can.
