The myth of expensive shafts

Doc Griffin is back today for the sixth episode of his series on Shaft Myths.
Today's discussion deals with the myth "The more expensive the shaft is the better it will perform". As Doc explains, that simply isn't true. There are five performance characterisitcs that a club fitter will use to determine the best shaft for a particular customer:
Mass. This is the overall weight of the shaft, measured in grams.
Overall Stiffness/Flex. Usually defined as the amount of stiffness near the butt end of the shaft.
The Bend Profile. When a shaft is under load, there are varying degrees of flex all along the length of the shaft.
Weight Distribution/Balance Point.
Tortional Stiffness. The degree to which the tip of the club will bend at impact.
According to Doc, there are no "bad" shafts that are sold as after market components. The level of quality from today's manufactuers is pretty high. However, a one of these shafst that does not properly match the customer's swing can become a bad shaft in a heartbeat if the fitter doesn't know his business.
Check out the video for some additional insights from Doc on what goes into building a shaft to a certain specification--I found it quite interesting.
