There is only one component in your golf equipment with which you make every shot: That is your golf ball. Yet we golfers often enough hear "I'm not good enough, the golf ball doesn't matter" -or- "I'll play the ball that's in my bag".
However, wear and tear and variations in golf ball performance will significantly alter your golf game, especially on shots to the green.
Continuity in your ball choice avoids fluctuations in performance and is an essential key to a more consistent and successful game.
