Awesome time fitting for the new 913 today at Miles of Golf (one of 5 Titleist regional centers).  All I got to say is for anyone buying a driver, find a fitter that uses the Trackman and every shaft imaginable..  Spent almost 2 hours trying everything from their stock shafts to the Graphite Designs to my previous on the 910. Hands down the new Phenon was the best for me gaining about 13 yards on average carrying. Couldn't be happier.  Only sucks that we have to wait until November!!
