I am not big on changing clubs often, as I finally changed irons after almost 15 years to some Mizuno forged cavity backs. I played Mizuno blades back in the early 80's when nobody had ever heard of them. I think they were MS-7 or 9 or something back then.
I have had the same 5 wood for about 8 years, and I only have 2 Taylor Made clubs, a 12 degree "2" wood SLDR, and a 22 degree hybrid SLDR. My driver is an old Orlimar Hip Ti 420 with an Aldila NV 55g shaft.
I have hit a lot of drivers over the last 10-12 years or so that I have had this Orlimar, and never found anything that was a definite improvement...........until the other day. This Taylor Made M2 is the real deal, and I'm not easily impressed. I played to a 3 hdcp most of my life, but don't play much anymore, and don't have a current handicap, but at age 68, still shoot in the 70's, and not from the senior tees. The M2 is the only driver that I have hit that launches the ball high enough for carry with not too much spin, which is a distance killer. To get the spin down, I have usually played lower lofted drivers, and they are harder to hit straight. The M2 wants to hit the ball high, straight, and long, and it sounds and feels great. I am impressed.
Enough to buy one? We shall see. If anyone is looking for a driver, check it out. It is at least worth a look.
