I want to purchase a new driver. My choice is the 917D2 or the new TS2. I have read much about both and I do not know where to turn. I have heard that the TS is a better driver, but I do not know if the kinks have been worked out of it yet. I know the 917D2 is a good performer and it is the last Titleist generation driver. Who can help with this decision!!! I would appreciate any advice, good I hope.....
