The VIRTUAL DEMO allows you to see the trajectory of the ball with the racquet given any shot paramenters you choose. You can compare to shots at once. The trajectory for any given racquet will be determined by the shot parameters but ALSO by the racquet specs. The trajectory is the result of the combination of all the specs. These are figured into the calculations:
To see different shots, simply change one or more of the specs. The specs that are different will be highlighted in the right hand racquet with a different color. Below, I changed the swing angle from 45 to 70 degrees.
