The lack of clamouring is a good sign. It indicates that the club are seeing things move forward with the council in a way they are happy with, and that the fans trust the ownership of the club.
If we were out on the streets shouting, it makes it all contentious and gets peoples backs up. If there is no need for that action, then it is a good thing.
In terms of a permanent 3,000 capacity venue, I'm sure they could upgrade the tent to achieve that. After all, most the major structure is demountable at the moment. Clad it, complete the bowl, and bobs your auntie's live in lover - a big improvement. If budget can be found to soup up the off ice facilities, and the sight lines, then it could be a decent home for years to come
Also, if they come up with the money to build a multi-purpose arena - there would be no need to actually decamp to there if there is a decent rink. If we could get close to filling the rink for most home games, then big games could be moved to the arena. I would rather have control of our home, rather than have to fit it around other events. Look at the problems the arena teams have securing ice time.
I think if they could seat 3000 in Ice Sheffield, Steelers would be tempted to move their home to there. I remember reading they struggle to break even on most home games in the Arena, and next season looking at closing off sections of the upper tier to try and improve the atmosphere.
