Club weight/length and its effect on the ball flights

There is no hard and fast rule when it comes to fitting a golfer with the correct total weight, head weight, butt weight and the overall balance of the club to achieve a higher percentage of centre hit and being in control of the three major factors that make the ball flies how you want it to.

There is no hard and fast rule when it comes to fitting a golfer with the correct total weight, head weight and the overall balance of the club to achieve a higher percentage of centre hit and being in control of the three major factors that make the ball flies how you want it to.

[In his TGM book, Homer Kelley discussed the three major factors that allow a golfer to hit the ball straight. Homer Kelley stated that a golfer needs to control the clubshaft, the clubhead and the clubface.]

Generally we see a change in club length, the total weight, head weight, butt weigh, shaft weight, moving the weights along the shaft to change the balance point can bring about an influence and change in club path, club face and centeredness of hit.

Not forgetting to mention that a lot of time when we reduce the shaft weight, we see an increase in club head speed.

Assuming the golfer’s clubface is aimed at the target, the following table shows the possibly issue with club length, total weight, head weight and weight distribution.

In our fitting practice, the best total weight, head weight, butt weight (balance point) is tested during the optimization process using lead tapes and butt weights.  When the best combination is found, the set of clubs will be built to MOI matched.  Our engineering tolerance is 1% which a normal human will not be able to perceive the difference.
