Forgetting the science for a moment. I have watched at least 6 authorized instructors teach and demonstrate hinging all the way from south carolina to california. I think I have the technique down fairly well. I know that the shot pattern is different and also useful. Therefore from that standpoint it is a valid teaching concept. Now in regard to science. It would be helpful to all of us for someone like Yoda to reveal his thoughts about trackman. Although I am a scientist I would caution all not to be overawed by science. After nearly 25 years of knowing about hinging, seeing hinging demonstrated and doing it myself the statement that there is no such thing is just laughable. Perhaps the available science is lacking. Now I am a good ping pong player and pride myself on the use of sandpaper or rubber paddles. Slams and cut shots produce various ball flights. Has that been studied also and is it relative? So when I read that science disproves hinging I just don't care frankly. My lesson using a trackman was very helpful so I believe it is a useful tool. So let the discussion continue, but for the "scientists" to snicker at the masters of the hinging art makes me lose respect for them.
