The Mizuno MP-53 Irons are advertised right on the Mizuno website as being made for golfers with a scratch to 14 handicap. This is pretty accurate and they are made for those that are better golfers.
Building on the legacy of Mizuno’s hugely popular MP series of irons the Grain Flow Forged MP-53 Irons has a head size and profile that appeal to the most skilled shot maker but uses a Diamond Muscle design combined with a Milled Pocket Cavity to offer a surprising level of stability on even off centre hits. It features an innovative Diamond Muscle design and a precision-milled, V-shaped pocket cavity. The modified U-grooves produce the ideal spin rate for maximum playability. The Mizuno MP-53 golf iron offers the perfect optical illusion for golfers, offering extreme forgiveness in a compact clubhead that would not look out of place in a tour bag.
If you have a high handicap you may find that you will struggle with this type of design. If you are floating right around the 14 handicap area you may struggle a little as well. Mizuno MP-53 Irons are designed to fit the better golfers and are made for scratch golfers and single digit handicap players.
