Go to a shop and try them out! By now its gonna be very common for places to have a few demo options. The only way to find the right club is to test them and to get fit! You won't be disappointed!!

I'd get fit. TS drivers are not cheap, so why guess? If you're just going to buy one off the rack, I believe the TS1 is most forgiving, and then right down the line, TS2,TS3 and the least forgiving is the TS4.

The technology is so different, even trying to match the loft and shaft characteristics empirically is no better than playing the slots. Besides Titleist Thursday free fitting events, most Titleist authorized pro shops will waive the full or most of the fitting fee to get the right one the first time. If you driver head speed is under 90-92 mph, good chance the fitter will compare the TS-1 and TS-2 for you.

As others have said go get fit. Titleist drivers have advanced and changed since then and I am guessing your swing has changed some since you got the 910 as well.

Get fit... No one here has seen you swing or seen your numbers... Might as well throw your money out the window!

Get fit! The TS2 wasn't for me. Found that out in a hurry via Trackman. But it was the club for the guy before me. Everybody is different and gets different results. Find a fitting center and go from there.

I played a round today at a course that we sometimes play but not our normal track. I have been driverless since my TM broke and currently waiting on the replacement. Anyway , back to today , got to the course and saw that they had bags of NEW Titleist rentals. I approached the club pro and asked about demo'ing just the TS driver. He handed me the TS 2 with the same shaft that I was gaming in my TM. I never hit so many fairways as I did today , the way I could control the ball off the tee was amazing and I immediately set up a fitting at an authorized dealer in my area. I am sold on this new Titleist driver and I will with out a doubt make the switch and yes I agree with all above comments to get fitted. But for me that TS 2 was the real deal. LAZERS I tell you...!!!
