Great thing about doing a Titleist Thursday fitting, they can put you on their monitor with the old club and then different set ups with TS2 and TS3. You will see the numbers on TrackMan. For me, i had already moved from 910 into 913, 915, and 917 with minor improvements every time. I am also fighting "father time" so my improvements are against a gradual slowing of my body. Love my new TS3.

I have recently upgraded my driver from the trusted 910 D2 to a new TS2 after being fit for it at the Titleist fitting centre at Eagles Nest GC. I have hit most driver offerings from other OEM's and held off my purchase until now with the TS2. Other OEM drivers adequately delivered similar distances off of the tee but the TS2 had a much more consistent dispersion and predictable ball flight for my swing. Unfortunately the approaching cold weather ended this years golf season. I cannot wait to get this new club out on the course in the spring.
Good luck with your search.

You will see a lot of forgiveness beetween TS and 910.
I passed from 910 to 915 and now TS, and I my opinion, this TS is the best driver of Titleist.
With my experience It is be longer than 915 and you will loose less distance on mishits.
