The SCHSL has asked a few teams to demo balls for the Finals. As you recall there have been problems in the past. The ball that has been approved for play this year is the Spaulding TF-3000. The balls are provided free for the championship games by Spaulding as part of a contract with SCHSL.
I strongly urge coaches to purchase one. It has a nice feel and does not stick to the turf like others. But, it is very lively.
