Thank you for posting this great guide!
The best thing about keeping a notebook is you will see just how erratic WTG has made play without using fancy balls. On Bethpage 18 with basically the same shot conditions yardage will yeild from 84yd/105yd driver to 132yd from 110yd driver a lot more than 5yds difference. Seems like the results from a specific shot configuration have changed dramatically, and are dependent on proximity of lie to bunkers,hole ect..
Identically configured bunker shots can go 0yds or 25yds might as well burn the notebook and close your eyes to shoot.
