GOLF SHAFT WEIGHT and Golfer

Shaft Weight is define by the total weight of the "raw shaft" itself. It is measured in grams. Most of the time when a club is purchased, somewhere on the shaft has a printing of number of gram(65 grams, 55 grams etc.). Most of the driver today come with graphite shaft and there are always printing on the shaft that classify the specification including the weight.
For instance, in shaft "ALDILA NV 65-R " Aldila is the brand, NV is the model, R meaning Regular Flex, and 65 is the weight in grams. "ALDILA NV 55-R" will be 10 grams lighter compare to 65-R.
In theory, the lighter the club is the faster the club-head speed base from same force of the energy(Golfer's Swing Energy). Therefore, to make a shaft lighter seems like a great idea to get more distance. That is why there are more and more clubs using lighter weight shafts today. However, lots of golfer actually might "lose the feel" of the club because the club itself is too light. Therefore, choosing a shaft that a golfer can "feel" during the swing is very important. Sometimes a golfer can actually play much better with a heavier shaft. (like Steel shaft in Driver) Typically, a male hitter will love to have something that is heavy in his hand to swing.
