Oh yeah, you gotta have a good set of balls for golf
Different balls are designed for different effects - some will provide a lot of spin and others little spin, some are designed for golfers with a great swing and others for those needing more speed, etc.
Here's a pretty good site that have reviews of balls and points out which type of golfer could find which kind of balls useful to the way they play or the way they want to play.
