Striker,
Not an easy one to definitively answer. Let me start with, Bridge FA will field teams in each gender age group where the numbers and ability allows.
With open tryouts, players can come from anywhere to play.
One of the basic principles of this is that a member club would not offer challenge level play. To cite the example that you make, it would be extremely unfortunate for the other 5 age groups (U13-U17) if MPSC was not a member of the alliance soley so the MPSC Sting could be assured to remain together.
Besides, if top to bottom on the roster they were the best group of players, then they would remain together.
None of this will truly be answered until Sunday, 15 May, at the Battery facilities.
