More than ever, getting professionally fit for the TS can make a difference. Besides all the cool stuff about the heads that is available online - The shaft matrix is getting a major make-over so be open to taking advantage of some of the newest technology. Look at different shaft lengths to optimize flight to your swing. Note Justin adjusted his by 1/8 of an inch on his way to winning at Firestone that cured his miss. Make sure to take the time to also trial different weights to get the feel exactly where you like it. Be it the TS2 or TS3. Under the #TSProject on under clubs, there are smiling faces holding signs with 3 mph/10 yards gains. Actually, I beat that (4 mph/13.5yards) with driver - but nothing was the same from my 917. Different shaft, loft, lie, length, flex, and head weighting. Now to wait for Christmas in October, unless released earlier.
