Pretty much spot on from OSB I'd say.
In truth the belief that I once held that the Higgs Trust was acting in the best interests of the club, has gone. If that ever was true, then clearly it's long since gone down the pan.
Conversely it's clear that SISU only ever set out to look after themselves. In itself though, that shouldn't stop a deal being done that suits both sides here.
It's ridiculous, imho, to suggest that Higgs should pay for something that might well end up seeing them out of pocket if the club moves on. Similarly, there's no reason SISU should stay at the Higgs centre if there's a better alternative. The intelligent thing to do here is to negotiate and see if there's a solution that benefits both sides, surely.
A longer rental deal and/or a contribution wouldn't seem a bad place to start - both sides will have to move from where they are now though, I'd guess. Might be better done outside of the public eye too, I suggest, and both sides might want to be a bit more professional regarding their habit of criticising the other in the local press.
