Had my TSR driver fitting today with a Titleist rep at a PGA Tour Superstore. Fitter was legit, brought his own Trackman and RCT balls which I was thrilled about. Expected to go with TSR2 and Ventus Blue 60X, ended up going with TSR4 and Graphite Design Tour AD IZ 60X.
My current setup is a 913 D3 with a Fujikura Fuel 60X from 2012.
My ball speed jumped from 169mph to 174mph as expected. The most eye opening data was the spin rate. I would frequently average 3100 rpm with my current setup and the TSR4 was producing 1900-2100 rpm and I was amazed. Very tight dispersion and unbelievable forgiveness on off-center hits.
With the higher launch and lower spin, my carry distance jumped from 275y, up to 300-305y.
Team Titleist member since the beginning, never leaving.
