What the Pros Say

"System-1 has helped me tremendously. I always had a good rhythm, but I never had a consistent rhythm. It's making my swing a lot more consistent, not just with the driver but the whole game. It's one rhythm for the whole game instead of having a quicker rhythm for irons or slower rhythm for the driver. "

Vijay Singh after winning the 2008 Deutsche Bank Championship.
