Flex: Callaway RCH 55 vs RCH 65
Flex is the amount of band that a golf shaft has during the swing. The more flexible a golf shaft is, the more it will bend. The more stiff a golf shaft is, the less it will bend during a swing.
In terms of flex, RCH 55 has regular and stiff options. The RCH 65 only has a stiff option. For those that don’t know, the more stiff flex options are better for those who have higher swing speeds whereas the more flexible options are better for those who have lower swing speeds.
Depending on what you are used to, these flex options may be the decision-making factor.
Length: Callaway RCH 55 vs RCH 65
In terms of length, both the RCH 55 and RCH 65 have the same length options of 46 inches. Believe it or not, this is quite long in comparison to other golf shaft lengths.
It is generally recommended that beginners and some intermedius use shorter golf shafts as they are much more forgiving. Longer golf shafts are much more difficult to use as they are harder to square on impact. Depending on your skill level, this may impact if you decide to go with a shorter shaft.
The USGA has a legal limit of 46 inches for any shafts aside from putter shafts. This means that any golf shaft that exceeds 46 inches in length is considered illegal. Both of these shafts are legal to use and are right on the cusp of the legal length.
Material: Callaway RCH 55 vs RCH 65
Another similarity between these golf shafts is the material that they are made out of. Both are made from graphite which is the lightest material a golf shaft can be made from. This means that you will be able to swing quickly and won’t be fatigued due to the weight of the material.
USGA Legal: RCH 55 vs RCH 65
It is important to know whether or not the shaft that you are using is legal. The USGA has very strict equipment rules, even for golf shafts. If the shaft breaks one USGA rule, then it is considered illegal to use.
According to the USGA, both the RCH 55 and RCH 65 are legal to use in any casual, high-level amateur, or professional golf outings.
