OK, who is DISA? They have a couple of teams.....but I never heard of them. And CFC has 2 teams.
I glanced thru the pairings so forgive my error. But you have 4 1 team clubs....and then a couple of more clubs that aren't considered traditional powers.
I guess this is my point. DISA and CFC pretty much have the same number of Final 4 teams as Bridge.
Also not trying to disrespect CFC or DISA. Obviously they are doing something right.
