Dear Abby,
I have a teammate, a fellow lefty that will only use low-grit high-performance balls on a medium volume house shot. Sure enough, every week he blows a hole in the pattern. I have mentioned it to him that he (and I) would be better served if he slowed his shot down a little bit and he throws a less aggressive/more mid performance type-of-ball - that the shot would hold up better for he and I. However, mentally he just can't get there. It throws his timing off. He does not want to adjust and people don't change. How does one get through to him the benefits of not blowing up the pattern with an such aggressive ball?
Signed,
