I do tee work everyday. I practice with those cheap softballs you get from walmart. They aren't as hollow and made of the same materials as real ones. Are they harder to hit farther than regular softballs? Also: does how far you hit the ball off a tee transfer to how far you will hit it in a live game? How do you tell the difference between a fly ball and a big pop up from off the tee? I have a lot of questions.
