Loved it

Beautiful looks, fantastic feel.

A classy MP-30-style throwback that blends the 241 blade and 243, with beautiful looks, classic Mizuno forged feel, and control as its calling card.

+ the facts · 6 pros · 2 cons
  • +Beautiful clean satin chrome look with a very thin top line and blade-like appearance
  • +Fantastic grain flow forged feel with copper underlay
  • +Traditional lofts (34-degree 7 iron, 46-degree pitching wedge), refreshing versus strong-lofted rivals
  • Not a distance iron; aimed squarely at control players
  • A fourth model in an already crowded Mizuno Pro lineup, so its slot can be confusing

For: The low-handicap player who wants control over distance and a blade look with a touch more playability than the pure blade

Liked it

That's the best feel yet

Tested head-to-head against the outgoing Pro 243, the S-3 delivered an even tighter dispersion and the purest, softest feel, trading a couple yards of carry and a bit of forgiveness for higher spin and a classic players profile.

+ the facts · 5 pros · 3 cons
  • +Slight edge in feel over the 243: softer, purer, a solid thud on good strikes
  • +Remarkably tight dispersion, somehow even smaller than the 243's
  • +Higher spin and steeper landing angle for control
  • Carried about two yards shorter than the Pro 243
  • A little less forgiving and less distance-oriented than the 243
  • Higher spin makes it less suited to windy conditions than the 243

For: Longtime Mizuno players who want a traditional, nostalgic players iron with the best feel

Liked it

I was very pleasantly surprised with the Munos

A pleasant surprise that nearly matched the P770: grain-flow-forged softness with a slightly firmer, more powerful strike, but smaller, less forgiving, a touch shorter and £250 more per set.

+ the facts · 6 pros · 4 cons
  • +Really nice soft feel from grain flow forging and the copper underlay, close to the P770
  • +Slightly firmer, more powerful feel behind the ball that he quite liked
  • +Sleeker, cleaner, more refined design than its predecessor
  • Thin top line and small head felt intimidating and nervy over the ball
  • A little less forgiving than the P770, with one shot coming up short on a mishit
  • A few yards shorter through the set

For: Better players who want a sleek compact look and Mizuno forged feel and will pay for it
