xSweetCarolinex: The balls make no difference to the sound at all
If you have ever played real golf before you will know that the cheap 'n nasty balls usually handed out at driving ranges have a totally different sound to a nice Titleist, Calloway or Nike. There are solid balls, 2-piece, 3-piece and 4-piece balls, they don't all sound the same. Having a balata or a surlyn cover will give it a different sound too.
So.... I was just being jovial saying they may have put Range Balls (DUDS) in your bag instead of the good ones...... understand now dear?
