Is bigger really better in drivers? Does it really create a more forgiving club? What is the truth
As you make the driver heads larger you move the center of gravity (COG) farther from the axis of rotation. The further the COG is from this axis, the more power/force it takes to bring the club head back to square. So, for the slower/weaker swinging golfer, the larger head is actually a hindrance to better golf. For the better golfer the ability to work the ball becomes an issue with the larger heads.
It’s not broadcast, but Nike makes a special driver head called the Nike Dymo 380 that A. Kim, T. Woods, and D. Duval (the possibility of P. Casey looms on the horizon) use. A few years ago, The Surge predicted that we would see a shift back to smaller heads, with the max topping out around 400cc. One of the best club makers in the world, Katsuhiro Miura, will not make a driver head larger than 390cc. It is his belief that this is the maximum size that allows a golfer to return the club head to square at impact with consistency and ease.
