Understanding shaft stiffness/flex, and "kickpoint" or "bend profile" I was discussing shaft stiffness/flex and kickpoint on another thread, http://www.badmintoncentral.com/for...or-Super-Wave-37-(SW37)?p=1665478#post1665478 but I thought I should start a new one specifically for it. So, after some reading up on "kickpoint" and "bend profile" which is more widely applied in golf shafts, I have a better understanding of how it applies to badminton rackets. In a nutshell, it doesn't provide more power either way whether high or low kick point, or stiff vs flex, but if you use the one that is matched to your swing then that is what will give you more power. It is your swing speed, acceleration, and release of your swing that ultimately determines whether it is better for you to use a high or low kick point, or flex vs stiff shaft. More specifically, it's all about having the racket face contact squarely with the bird being optimally timed at the point of strike for best power transfer. Hence, the advanced player with a fast, rapidly accelerated, delayed release (ie compact) swing will get better power from a stiff shaft with high kick point closer to the T joint. Because the swing is fast, the racket face has to move fast to contact squarely with the bird at strike. On the other hand, the beginner with a slower swing with no acceleration and early release (ie longer) swing will benefit from a flex shaft with low kick point closer to the handle. Of course these are just extremes and most people will fall into the spectrum between. If a fast swinger tries to use a flex shaft with low kickpoint, he'll overpower the shaft as the racket face will be lagging behind at point of strike, hence the bird will not be hit squarely. What the fast swinger will then consciously or subconsciously do is adapt his swing by "whipping" the racket face thru the bird so that the racket face has some more time to accelerate forward to strike the bird more squarely. However, the price he pays is that he will lose the immediacy and control of the stiffer shaft that he is used to using. **Also, advanced players, especially in doubles where speed and reaction is critical, will prefer stiffer balanced rackets because of lesser lag of the racket face, allowing shots to be repelled faster eg. drives, smashes, smash returns. **Another corollary arising out of this is that advanced players also benefit from higher tension as the stringbed is part of the racket face and shaft system. But that's another thread... What do you fellas think?
