I've been golfing 30+ years shooting in the low 90's to high 80's...I practice daily at Riverwalk Golf Course in San Diego, Ca...I owe my swing transformation to Devin Fitzmaurice, partner of SDGI (San Diego Golf Institute)...Lately, I've been scoring in the low 80's. Today, I scored 76 at Mt. Woodson, my lowest score at that course! I've been using Pro V1 exclusively for the past 8 months...Great ball! I've played competitor balls over the years...No more!!! Thanks to your ball I recorded my FIRST hole-in-one today at Mt. Woodson. Thank you. Sincerely, Miles Weaver, 62 years old...
