"Using the TaylorMade custom fitting option when I purchased this driver recently made all the difference in the world. My prior driver, 2016 M2 model, was decent, yet the stock shaft provide performance characteristics I didn't enjoy (High launch angle / High Spin rate). Since receiving the 2017 M2 D-type driver with a low-mid lauch/low spin shaft, I realized a 30+ yards gain in my drives this past weekend. On several occasions, I out-drove my competition by 50+ yards (paired with another 9-handicapper). My club-head speed is in the 95-100 mph range, and at 56 yo, I have thoroughly enjoyed the added performance."
