This page displays frames from three videos that show the results of properly fitting a player for the golf shaft with the FitChip and the swing timing process used by Lotus Golf.
The club head Lags the soft shaft The club head leads the stiff shaft
The correct shaft is straight at impact
These three frames from video of this player hitting three different stiffness/frequency shafts shows the value of fitting by swing timing. no other fitting system currently in use concerns itself with getting the shaft back to straight at impact. The club has its best combination of accuracy and clubhead speed when the shaft is back to straight. When the head is laging the head is not up to full speed and when it is leading it is already losing speed as well as impact efficency. Accuracy is also compremised when the shaft is not straight.
The yellow lines in the pictures show the progression of the shaft flex durning the swing. The silver streakes are caused by aluminum foil wraped on the shaft and head to indicate the location of the head and flex of the shaft.
