Flex: KBS Max 85 vs KBS Max 80
One of the first differences between the 80 and 85 is that the 85 only offers stiff flex, whereas the 80 offers regular, staff, and extra stiff flex options. So the 80 offers 2 additional flex options that aren’t available with the 85. These additional options are great for those with average and very above average swing speeds.
The 80 offers a more extensive flex variety making it a better choice for most golfers.
Weight: KBS Max 85 vs KBS Max 80
In terms of weight, the 85 is significantly lighter than the 80. The 85 Wii is 85 g whereas the 80 weighs about 102 g. This is a substantial difference between the two and this difference will have an impact on your overall performance. For the most part, a heavier golf shaft is easier to control and will help with your accuracy. A lighter golf shaft will be easier to swing and help increase your overall distance.
Depending on what you would like to approve these are things to consider.
Length: KBS Max 85 vs KBS Max 80
Another difference between these two is the length. The 85 comes in a 41 inch length and the 80 comes in a 42 inch length. That means there is a 1 inch difference between both of these. This 1 inch difference will likely not make a huge impact overall on your performance, however if you are used to a longer golf shaft then you may want to use 80 instead of the 85.
The USGA has a 46 inch limit on golf shafts if any golf shaft exceeds the limit then it is considered illegal. Neither of these golf shafts exceed this limit.
Legal: KBS Max 85 vs KBS Max 80
It’s important to know whether or not the golf equipment you are using is considered legal. The USGA has pretty strict rules on golf equipment. Both the 80 and 85 are considered legal, which means that you can use them in any casual, high-level amateur, or professional golf outings.
