After 60 games, 95%+ of the balls being sold will show definite signs of a track and other wear and tear, especially if this is the only ball you use. Old wood lanes will affect a ball more than synthetics. Old synthetics will affect a ball more than new ones. Ball returns from the back of the pinsetter to the underground path to the lifter mechanism can all affect a ball, some more, some less.
About the only way to reduce this wear is to use a plastic ball as a spare ball on all spares, as a lot of people do. Using your strike ball as a spare ball is definitely one way to reduce its life expectancy.
All resin and particle balls are in the same general hardness range, 72-75, with a very few in the 76-78 range. Most plastic balls are slightly harder, and since they spin/skid (as opposed to roll) most of the way down the lane, they wear less than resin.
You can also try plain urethane balls; they will generally wear better than resin balls.
