Most golfers have a problem slicing their Driver, but not the other clubs. This would, of course, not happen if all the clubs were matched. In a matched set of clubs, all the clubs will go straight, as long as you can hit any one club straight.  So why does the Driver slice? Because the moment of inertia of the Driver is too large compared to its overall weight.  This causes the hands to be too far forward at impact. In other words, you are hitting the ball with an open face.  As your hands are too far forward at impact position they are now on a path towards the left, away from the ball, causing a slice spin.

The large moment of inertia of the modern Driver is mainly caused by the increased length of the Driver.  In an attempt by golf club manufacturers to produce more distance, they have increased the length of the Driver.  This may work for you if you are able to steer the club with your wrists into a position where you can control the ball flight.  Steering should not be necessary.  It complicates the game as you have to steer each club differently, as they are not matched.  If your clubs are properly matched they should all behave as intended with relaxed wrists.  Relaxed wrists will also provide more distance.

Golf club manufacturers are fighting the open face by manufacturing Drivers with a closed face.  However, the slice spin remains as your hands are moving right to left at impact.  Some club manufacturers try to further reduce the slice by adding movable dead weight to the club heads.  The dead weight further increases the moment of inertia of the club which again will add to the problem.  When moving the weights around on the clubhead the center of gravity of the clubhead is no longer aligned with the geometric sweet spot, causing further problems.  This all adds up to a very unstable condition.  It is like trying to balance a ball on top of another ball.

When adding weight to the grip end of the club, your hands will slow down slightly.  And due to the added weight, you body will create more kinetic energy.  This added kinetic energy translates to added club head speed.  Meaning that your club will release faster making your club head catch up with your hands.  The BioMatch method of matching golf clubs calculates the exact weight to be added to each of your clubs for the club head to catch up with your hands exactly at the point of impact. 

The BioMatch method calculates the specific weight to be added to the grip end of all your clubs.  The BioMatch system is available online at www.rational-golf.com.  The weights that are specified in the BioMatch Report can be ordered by a click of a button.  The weights are easily installed with the accompanying tool.

It is a lot easier to learn and maintain one swing rather than 13.  BioMatch does magic to any golfer´s game.
