"His reply was that he didn't care about the dings"
That is my wife's M.O. when she plays / rides. She takes the damn covers off, and it
drives me crazy! I ask her "Do you WANT these nice Ping clubs of yours to get all dinged up so they look like junk?
If so, then keep on leaving those covers off and that's what'll happen!" Of course, it falls on deaf ears.
As a compromise, she leaves every other cover off so that when the clubs rattle together, hopefully they'll be bumping into a club with a cover on it. If we walk, I guess I don't care, as the bumping together is minimal. My clubs
look like new b/c I walk 95% of the time.
