Driver Mass and Shaft Length on Initial Golf Ball Launch Conditions: A
Designed Experimental Study," Procedia Engineering, Vol. 34, pp. 379-384.

Description: Randomized Block design comparing 4 golf club drivers in
6 subjects. Responses: Backspin (RPM), Total Distance (meters), Ball
Speed (KPH), and Launch Angle (degrees).
Driver 1: Mass=270g, Length=117.5cm
Driver 2: Mass=290g, Length=116.2cm
Driver 3: Mass=310g, Length=115.0cm
Driver 4: Mass=340g, Length=113.4cm
