Been using Titleist drivers for years. Had a TSI2 and hit it very good but I went to the TSR2 this year and it's just hard to tell you how much improvement this club is over past drivers. It is so smooth and straight that I soon started cranking up the speed.. can't believe how far and straight I am hitting now. Play my home course all the time so I know where my drives have been.... not so perfect hits are better than TSI2 and flush center hits, I am getting 15 to 20 yards more. Very straight. I'm 77 and I'm getting distance like I did 20 yrs ago. Put in the Project X rip tide even flow shaft 50g 6.0 . Thank you Titleist...
