As the away credits doesn't account for the amount of aways to attended (more the purchases) , it's not a true reprasentaive of loyalist fans, fact
It's the best option of those available. Personally i think it's a load of rubbish and totally overblown, this idea that people buy aways and never go, or sell a lot of the tickets they buy. I go to away games and see a load of the same faces time after time. You tend to find that those who do buy aways and sell them also go to an awful lot.
I bought about 12 away tickets last year, sold 3 and went to 9 games. Those 3 tickets were sold to people who otherwise wouldn't have been able to see a match, including a guy whose first Everton game was watching us beat United at Old Trafford. That's hardly a crap game, and i couldn't go due to unforeseen circumstances.
