Changing ball

[SAK]

After selecting a game ball for the game team A requests to change the ball to a ball that has more air and actually bounces too high. The request was denied. After returning from the locker room at halftime the table bounces the ball to me to for the throw-in to begin the 3rd quarter. I bounce the ball once and determine that the ball has been changed. (Obviously this is why we give the game ball to the table, so that we don't have to deal with this situation). I run over and ask for the ball that was selected to begin the game, the table identifies the ball and we go on.

My questions are the following, what are the rules about changing balls in the middle of the game. It is my belief that as per 12-2-3 I have the right and responsibility to select the ball however I don't see any thing that would prevent us from changing a game ball to one that still meets the rules and for example has a better grip. Finally, there was no penalty given to the home team, the team that took credit for changing the game ball, but would anyone have considered this a non-sporting or disrespecting a game official as they knowingly changed balls to one that did not meet specifications.
