For me, depends on the ball's OOB and where I'm using it.
Some lane surfaces wear on a ball more than others: Guardian vs Anvillane. The Guardian overlay is much rougher on balls (Maybe 20 games) than the lowest friction, fully synthetic Anvillane surface (Maybe 40 games).
Some balls, P4000 grit matte finish surface, (Maybe 15 games) will wear mmore rapidly than others: 800 grit + polish surface, (Maybe 25 games) will wear more radidly than others: 800 grit matte finish surface (Maybe 40 games).
