Clubs usually have policies regarding player rotation so maybe  check with your head coach.  I prefer to rotate players fairly during the season and play the best combinations in finals but it does depend on what grade the team is in.  Low grade = not so much focus on the best team and more about fairness, enjoyment and achieving training goals. High grade = rotate with aim to keep strong combinations on court with incentive for improvement of less skilled players to achieve more time on court.

I have mostly found that with 9 players rotating with 1/2 game rather than 3 quarters is less disruptive to game flow. I have had one team where 3 quarter rotations worked well but they were a very versatile team and had no trouble adapting to frequent player changeovers.  So what I am saying is that it depends on strength and versatility of your players and trial & error as to what works best.
