Good post. If I remember correctly this all started when discussing what your club can or cannot afford. The point I'm trying to make is that despite the smoke, I still think that overall they are a benefit to the club financially as well, with or without pyro.
Whilst the win is huge for you I'm sure, the high will end and I can't imagine you'll have 7-8000 at every game? Here in Trondheim there are many people who choose to go to the stadium instead of watching it on TV, simply because of the atmosphere we create at our stand. Over a season, that will be quite a big sum for the club because of the influence the most passionate have on the rest.
I think the same thing can happen in Perth and when you look at the positives and negatives, these lads will not have been a burden to the club's finances.
