After making your selections we will need to know what length to build the club. Please state the length in "notes" at checkout. There are 2 methods of measuring; to PGA or Long Drive regulations, to use a driver in club competition the maximum length permitted is 48" and is measured in a PGA set up jig. For Long Drive competition the maximum length is 50" (measured in a pendulum method) there is only approximately 5/8ths of an inch difference between the 2 finished clubs, but it is important to select the correct length for your requirements. If you need further advise please mail us.
