The new rage for 2007 is square headed drivers. Every manufacturer is scrambling to release their version of the square head. But is it really "hip to be square"? or is this just another marketing gimmick promising everyone straighter drives on the golf course.To really know, you need to understand moment of inertia or MOI as the golf industry calls it. MOI is a property of physics that indicates the relative difference in how easy or difficult it will be to set any object in motion about a defined axis of rotation. That was for all you physics majors. Now for the rest of us golfers, MOI is the term applied to a clubhead's resistance to twisting when the ball is struck. For example, your swing is a little off and you hit the ball on the toe of the clubhead. A clubhead with a higher MOI will twist less as a result of the mis-hit, creating a better chance that the ball will still go where you intended and with less loss of distance. So how to the manufacturers increase MOI? The simple answers is perimeter weighting. The key to increasing MOI is relocating as much weight as possible as far away from the clubhead's center of gravity. The new square shape has allowed manufacturers to create extreme weighting in the corners of the clubhead, outside the weighting zone of a traditional driver. This has increased the MOI, thus creating a driver more forgiving and overall provides for longer straighter drives.As most manufacturers are launching these new club head with price tags of over $400, TourGolfClubs has introduced a line of square head golf clubs that rival the top name brands in features and performance but at a quarter of the price.
