After much thought, research, a titleist fitting in March, I finally ordered a New TSR1 Driver. My fitting was not a good one, only because I was not swinging well at all. In the middle of some swing changes and I thought I was getting the correction down. But put me inside in front of a screen and I fall apart. Plus I became very dehydrated during the session. So my recommendation was TSR1 12 degree, With MMT 40 - R2 flex. I did not really agree with that. Eventually I contacted my Titleist fitter and he agreed to re-do my fitting. But we could not get together before my new pacemaker implantation, which was 6 weeks ago. I've had to many hours of research to admit. But after comparing what I swing now, my ave. swing speed and wanting more height and distance, I caved and ordered the club through my Pro at the club. The only thing I changed was I switched the R2 for Reg Flex This is my first Titleist club! I am very excited. Next will be the 15 then either a 18 or 26 Hybrid. The goal is to fill up the bag with all Titleist Gear. Let me say the 2024 Prov1 yellow ball, feels nice, flys nice and you can see it a mile away. Thanks Titleist for the 3 + 1 deal!
