It's not about speed it's about ball flight and roll. With a medium draw a 100 mph swing will carry about 255 yards and roll up to 35 yards. A 105 mph swing with the same draw will go 260 carry averaging 275 yards to 300 every time. If you hit a high ball or fade it could be 240 or less it's pretty drastic. Pros swing 118 mph and can hit a fade 275 carry and like the control if you like 235 carry and and enjoy a fade with control by all means play from the white tees.
