Impact tape on your clubface will show you what part of the face most often contacts the ball. Important information is then deduced from this data to determine your clubs. With that in mind, the following terms are reduced and explained so that you can better understand the concepts. Golf clubs in a set also need to be tuned to one another, so the different shafts vibrate the same at impact. Frequency matching is the process of equalizing the shafts' vibration rates.
Proponents say the result is a consistent feel from club to club at impact.
A clubshaft bends while you swing it. Obviously, your swing also affects the results. No yawns here. This is the optimal combination of forward momentum and backspin. But not enough to get caught in the wind and lose distance.
