Query: easy to dent

While the bat has good performance for a single wall bat overall it lacks in durablity. In a 60 and over league ware the players are much weaker than the player that are 30 or 40 years old, the bats don't stand up more than a couple of months. In fact My bat was egge shape in a couple of games. Regardless of how careful I was to turn it each time I used it.Now I'm not a home run hitter [I'm happy to find a hole in the infield.]I'm 180 pounds and 78 years old, which should limit my ability to dent bats.
