I am 70 years old and have had the TS1 Driver in my bag 2 weeks, having changed from cally Epic.
It is, without a doubt, the best driver decision I have ever made. During my last round I had 4 drives exceeding 270 yards, with one over 290.
If you have a moderate swing speed and aren’t using this driver, you are costing yourself distance.
Before you ask, it has a regular flex shaft.
