Lets face it, the FA is the biggest competition we get to play in every season, its our chance for a small team like us to play against the 'big' boys in the prem. This means us winning the match Tuesday to get through. The same FA cup that if we were in the conference and this happened everyone would be thankful we have another chance to play the game at home....now its just a 'burden', blame the credit crunch as you will it'l only go so far.
Instead of thinking "i've already paid for this match once" why not thinlk of it as a 2nd leg, or just another fixture in the season. People say they can't afford to pay the full price again yet if we get to the next round thats another full price ticket they'l have to fork out, yet thats never mentioned.
As an answer to the very philosophic question no matter what the club decide I still think the fans should turn up and support the team hopefully getting us a big pay day in the 3rd round so our small club can afford to give back to the fans! 2 Years ago we'd have had a larger attendance than today without a doubt!
