Swing Speed and Frequency Analysis

Find Your Flex
What this means to you is that you should solve the equation backwards. Find a club that you hit well, get it tested. You will then know a frequency that you like for a specific club. The frequency will be a numerical value - "cycles per minute". You will then have a "dot on the chart". An experienced clubmaker can build your set of clubs based on that frequency.

However, there is one more "artistic" problem. The concept of "playing flex" implies that even if two shafts measure the same frequency, they may not "play the same" depending on other variables that relate to bend point, shaft material, temperature (no fooling!) and the psychological profile of the golfer. Your "perfect flex" will be different for different shafts. Do not expect to find a "magic number" that is good across all shafts. A "frequency that fits" is only good for the shaft type that was tested.

In the end, you will go with what "feels best". It stands to reason that making that choice requires "feeling" a variety of choices. We can't overemphasize the value of testing a variety of clubs to help you discover what feels best. On average, this is not the method employed by the professional salesmen whose goal is, once you have presented yourself qualified and ready-to-buy, wants to close the sale as quickly as possible.
