  1. I’m in the market for some new forged irons. I currently have Titleist
    forged irons and they are amazing! I have only had McGregor and Titleist
    irons. I’m wanting to try out other brands before I buy again since I keep
    irons for over a decade at a time and I want to see if there are any other
    brands that fit me better as a player. How do the Mizuno forged irons
    compare to the Titleist? Thank you for your time.

  3. Mizuno’s H4 irons dropped my index 4 points in the last 18mo. I love
    Mizuno products and how everything they make is top of the line. Keep up
    the great work!!! 

  5. Mizuno won’t chase players at any level. Whether top amateurs or
    professionals Mizuno is more likely to deal with players who already play
    its equipment. Other brands have an increasingly aggressive approach – so
    there are fewer players to go around. Although there is still a very
    strong following of Mizuno equipment amongst top amateurs.

  6. I was fitted and now own a set of MP-H4 3-PW irons (Jun ’14); the first set
    of pro irons I’ve ever had. My old set of Taylormade Burner Plus 4-PW
    didn’t conform to the new USGA groove specs. My game wasn’t getting better
    and I decided it was time for a change. The first hits of my MPs on the
    range told me I had something special like nothing ever before. When I
    played them, I realized several things; the forgiving & hot-faced TM’s had
    caused me to become lazy. So right off with the MPs, I was not generating
    enough clubhead speed to equal my TM iron distances (8-iron: 155-160 yds).
    I hit balls until I figured this out. Choking down a bit and rotating
    faster did the trick. I am working up to and almost back to where I was
    with the TMs. Now I am starting to feel how I can work the ball where with
    the TMs it would not be so easy. The MP-H4s are well made, feel solid and
    have literally made me a better player. I play to a 2.5 Hdcp and these
    clubs in time will get me on down a notch or two. I’m sure it will take me
    a season to really dial them in, but already after just 4 rounds, I am sold
    on the quality of these irons. Coincidentally, the swing adjustments that
    forced my iron swing-speed up have also improved my distance on the driver,
    3-met & 3-brid. The pro fitting of the irons helped I’m sure. I appreciate
    what the Mizuno company has offered golfers and I am sure to be playing
    their clubs for a very long time.

  10. PING Baby. If Mizunos so good, how come almost no players use them on PGA?.
    I went to a top amateur tourney, no Mizunos, Not one set and I checked all.
    So dont give me the “we dont pay execuse”!!!. Fact is all the top brands
    PING/Titleist/Taylormade,,,,all the same!.

  13. This is not stamping. Did you see the shape of the billet, then the shape
    after that 3x pounding? Stamping mostly refers to shaping of sheet metal.
    You don’t alter the grain density with stamping.

  23. I thought forged steel was simply a solid piece of metal that is cut
    (forged) to the final shape, not “stamped” or “pounded” into shape? Like a
    sculptor would chisel marble into to a sculpture…?

  24. And conversely forging marble wouldn’t work because you’d just be breaking
    up the crystal lattice. It’s not very malleable. Forging is done on
    malleable materials as a stronger but usually more costly alternative to
    casting and milling.

  25. You should make Chris his own YouTube channel where we can just talk about
    every golf club and how it’s made and it’s features and comparing them,
    just for ages
