How Long Do You Play With Single Ball?

Once it gets scuffed up, it goes into the practice bag, or bad game pocket that will only come out when it doesn't matter. What I hate it when I bounce one off the cart path and sacrifice a ball for one shot where I might get an extra 20 yards off the bounce.

About 25-50 shots on average, and not by choice.

I'll play with same ball until either I lose it or if the performance of the ball has been influenced by any nicks or cuts.
