I played on a Wednesday evening league in the early 1990's and one evening at the course, I shot a 39 and broke forty for the first time ever! I only played one golf ball that evening with no penalties and it was a Titleist. I had five pars and four bogies. But it was the ball that made the difference. Prior to that time, I had really never broken 45 let alone 40. Sincerely, William Reid
