I bought a 917 D-2 driver three days ago and it is FANTASTIC!!!! Titleist really did their homework. THANKS! A special "shout-out" to Mike Morgan, sales rep. @ Arbor Trace G.C. in Marion In. Because of his generosity (a new Titleist hat and a short sleeve of the new ProV & ProV1x balls) I decided to purchase the new driver. THANKS MIKE, you are "special!! S.D. Berry
