Hello everyone! Happy Holidays and Happy New Year! Well we went to Pga Superstore today and brought my 915 D2 to hit with the monitor as I wanted to see if my swing speed is the same as I am older now and yes it's still is at 100 mph. While I was there I wanted to compare the new 917 D2 at 9.5 degree against my current driver. I can honesty say I gained 10 plus yards overall and my spin was a lot lower! I had the weight in the draw setting and shaft was A1. I was very impressed with the performance on the new driver that I bought and now it is in my bag. Tomorrow I will be going to the course to put her in play! All my clubs are Titleist! Keep up the great work and to a Happy, Healthy and Great Golf year for 2017!
