It’s been 11 years since my last proper driver fitting. I remember it well - had been playing a TM R7 425, and wanted to switch back to Titleist. Took experimentation with 4 shafts until I found the right one for a 910 D3. Well, I’ve since had a 913 D3, 915 D3 and now 917 D3. I’ve been using the same shaft for the last decade. Tomorrow, I hope to find out what all the fuss is about with these TSR drivers! Best part, I’ve been hitting my 917D3 well if late, so hopefully I’ll have that swing tomorrow and will be able to see first hand how the latest tech will help me improve my game.
