Toulouse is very serious, and wants to be in it for the long term, has a good junior structure and a relationship with other regional clubs as possible feeders, but is a bit suspect on the financial side at he moment (though that may be because of the bad economic climate we are all facing).
Paris SF is a completely different kind of candidate. Its backers have loads of casino money, and the prospect of a good stadium in the national capital, but SF has no junior structures yet, and its long term commitment is not as certain as that of the Toulouse management .
This makes it a very hard choice for the RFL, whether they are considering a French club for 2012 or 2015.
You can't turn down big money men and you can't turn down any area where junior RL can be strong.
Damn shame both ingredients aren't in one prospect.
