Flex: True Temper AMT Red R300 vs AMT Red S300
One of the first differences between these two shafts is the flex. The AMT Red R300 is regular flex and the AMT Red S300 is stiff flex. Regular flex is better for those who have average swing speeds (around 90 mph), whereas stiff flex is better for those who have a bit higher than average swing speeds.
If you have average swing speeds, then the R300 will be better for you, if you have faster swing speeds, then the S300 will be better for you.
Length: True Temper AMT Red R300 vs AMT Red S300
One similarity between these two is the length. Both have a length that spans from 36.5 to 39.5 inches. This is pretty standard for club length. These lengths are suitable for a wide variety of golfers.
For those that do not know, the USGA has a limit on golf shaft length. A shaft cannot exceed 46 inches. Neither of these shafts exceed 46 inches therefore they are legal.
Weight: True Temper AMT Red R300 vs AMT Red S300
A slight difference between these two is the weight options. The R300 ranges from 94 grams to 106 grams and the S300 ranges from 95 grams to 107 grams. Essentially, there is a 1 g difference between the weights of these shacks. This one gram difference will likely not impact performance in any way, so they are quite similar in terms of weight.
Launch: True Temper AMT Red R300 vs AMT Red S300
Another similarity between these two is the launch. Both have a high launch which means that these are designed to give you a lot of height on impact. If you are looking for a shaft that will help you get the ball into the air, then either of these are a good option for you.
If you are not looking for a shaft that gets height, then you may want to look elsewhere as there is no other options with these two shafts.
Spin: True Temper AMT Red R300 vs AMT Red S300
Yet another similarity between these two is the spin. Both are designed to generate a lot of spin on the ball which will help you break through any type of wind influence there is. It will also help you generate a bit more speed and distance on the ball given that there is more spin generated.
USGA Legal: True Temper AMT Red R300 vs AMT Red S300
It is important to know whether or not a golf shaft is legal. The USGA has a long list of rules that must be followed. According to the USGA both the R300 and S300 are legal to use in any casual, high-level amateur or professional golf outings.
