    The new Titleist TSi metals represent the best of Titleist’s peerless pursuit of speed - continually investing in new materials and technologies to push the boundaries of fast.

    And one of the biggest advancements you'll see the next time you pick up a TSi driver is the small "ATI" logo on the bottom left corner of the face - representing ATI 425 Aerospace Titanium, a unique alloy never before used in golf equipment (until now). 

    So, what exactly is ATI 425 and why is this unique alloy key to creating a driver face that delivers increased ball speed at every point of contact?

    Hear from our Golf Club R&D Team on why ATI 425 helps make the new TSi Drivers the longest and straightest drivers we've ever made.

    Unfortunately, I'm from that other era, when woods were wood. Woods will always be "woods" to me. But, wait. Why would you call them metals? Shouldn't you call them 3,5 and 7 carbon fibers? or composites? Bazinga!

    Or why not call them for their application - driver, fairway, hybrid; i.e., #3 fairway, 19 degree hybrid.
    "I am trying to decide whether I should hit my driver or my #3 fairway on this short par 4..."

    Every once in awhile you’ll hear an announcer refer to a 3-metal or 5-metal on the weekend coverage. That said, I still refer to them as woods. I have a TSi2 driver, 16.5, and 21 and I am looking forward to adding a couple of TSi2 hybrids to the mix as soon as they’re released.

    It's minus 5 this am, I've been at home far too long, the outdoor range sheds are way too cold and I'm bored, so....

    Can we still be golfers using drivers/fairways using club heads of metal? - Real Golfers use persimmon.

    Although I'm perfectly happy being a wimp with metals. I have a 1980 set of Tour Titleist clubs with persimmon heads. Fun to use, difficult as h*@l to hit.

    I got fit and bought the TSi 3 Driver and TSi 3 15 degree fairway in November. I've had a chance to hit them at the driving range and they feel great. Can't wait until the snow melts and I can put them into play. Nice to know Titleist continues to find ways to make their clubs even better for us. Thanks.

    I just bought a new TS2 hybrid and 3 wood When I went to register them it came back unable to find product. Also a demo hybrid came back as a 816 . Can someone explain why this is. Both bought at a golf town
