Mix of both, owned with our teams in baseball and softball, and different facility use. You'd also be surprised at how many aluminum bats we dented.I use to hit them (baseballs) a lot when I was a kid but that was with aluminum bats that wouldn't break if you hit 5 lb rocks..Would you say that you were using good condition dimples or was a lot of your hitting in facilities where you had no idea how the balls were taken care of?
