You can't watch a golf tournament on television this year, or pick up a golf magazine,  without hearing  about how all the pros are hitting today's newly designed golf balls 15 or 20 yards farther, or how they produce more spin for holding those tight greens.  Good for them, but experts are quick to warn amateurs that they shouldn't expect as big of a gain if they switch to these new high tech golf balls.  Why?  These new golf balls react to the incredibly high clubhead swing speed today's golf pros generate, whereas, most amateurs' club speed is probably slower than the pros, so naturally they can expect to pick up less distance and less backspin than the pros.
