Flex: Project X LS vs Project X LZ
The first difference between the alpha and the beta is that the alpha has three flex options and the beta has four flex options. The additional flex option that comes with the beta is the regular flex. This means that if you are used to using regular flex, then the beta is right for you. Otherwise, both offer a wide variety of flex options.
Weight: Project X LS vs Project X LZ
The next difference between the alpha and the Beta is the weight options. The alpha ranges from 120 g to 130 g whereas the beta ranges from 110 g to 125 g. So, the alpha has heavier shaft options and the Beta has lighter shaft options. Depending on what you prefer, one of these options may be better for you than the other. Heavier shafts tend to increase the amount of control you have and lighter shafts tend to increase the amount of distance you can get. Once again, depending on what you’re looking to improve this makes a difference.
Length: Project X LS vs Project X LZ
One similarity that they have is that they both have the same length options. Both range from 36.5 inches to 40.5 inches. This is quite a wide range and is suitable for many different golfers. The USGA has a 46 inch limit on golf clubs. In other words, a golf club is not allowed to exceed 46 inches in length. Neither the alpha nor the beta exceed this limit.
USGA Legal: Project X LS vs Project X LZ
It’s important to know whether or not the golf equipment you are using is considered legal. The USGA has very strict rules on what is considered legal. According to the USGA both the Alpha and the beta are legal to use in any casual, high-level amateur, or professional golf outings.
