I know some associations don't allow players to play in different divisions with different ratings in the same tourney.
For example, does SSUSA have a rule against a 55AAA player playing 60M in the same tourney as long as player is eligible to play 60s?
JohnO28 ... NO prohibition against "double rostering" so long as it's "vertical" ... Between age groups, if otherwise eligible, is fine ... CANNOT "horizontal" double roster and be on two rosters in the SAME age division ...
