-the cheaper balls dont last much after opening the can; 1x match and 1x-2x practice/s within days of each other
-the more premium balls last about double that ,(respectively speaking) but again all within days of opening
-if you dont play very frequently, i would open a normal cheap-o can everytime i visit the courts
-no sense buying premium balls if they are going to go "flat" by the time you get to the courts again
-wilson and/or penn balls would be my suggestion to weekend warriors
-btw,
@Bilders wilson came out with wilson.TRINITY balls
-that might be something you might like
-its a different type of ball that last a longer time, more so than conventional tennis balls
