Can you back up your claim or not? Why do you continue to change the subject. Can you provide proof to your statement copied below or not?? If not then I guess we are to assume that you guys just make stuff up as you go along. I guess that is normal in the golf business.
The action of hitting down on the ball pinches the golf ball between the club face and ground, this "pinching" action creates spin on the golf ball - the spin creates the lift.
Put up or shut up!!
