Andrew Rice was "handed a pristine collection of older model Titleist golf balls" that included Tour Balata 100's, Professional 90's and early model Pro V1's.
He enlisted a consistent driver in Atlantic Golf Club's Zack Brady and had him hit six shots with the old balls and the current Pro-V model on the Trackman. And guess what they found?
"The huge leap in distance off the tee on the PGATour in 2000 is due to only one thing – the introduction of the Pro V1." An increase in distance of almost 10% over the scuff resistant Professional.
The Tour Balata averaged 261.6 yds, the Professional 90 262.1 yds, the Pro-V1 392 286.4 yds and the current Pro-V1 298.4 yards.
