Category: Max Game-Improvement Irons
Price: $599, steel; $699, graphite

WE TESTED: 4-6 hybrids with Grafalloy ProLaunch Blue graphite shaft and 7-GW with True Temper Performance 85 steel shaft
KEY TECHNOLOGIES: Three hybrids (4-6) and two transitional hybrids (7-8) bridge the gap to the short irons (9-GW). Hybrids have a cutout groove along the crown and sole (“velocity slot technology”) to increase the face’s springlike effect for faster ball speeds. Low-profile 7-8 “irons” have a low CG (to improve launch), added perimeter weighting, and a thin, light face for power.

OUR TESTERS SAY: One of the most forgiving irons in its class. High marks for playability and feel.

PROS
PLAYABILITY: Clubs knife through grass and don’t overcorrect from uneven lies; heavy perimeter weighting and added sole weight get shots airborne easily from rough; hybrid long irons help vertically challenged players.
ACCURACY/FORGIVENESS: Short irons are pinseekers; head weight causes the face to square up at impact; very good directional control.
DISTANCE CONTROL: Muscular clubs pack a punch—thin hits and other off-center shots produce above-average distance.
FEEL: Heavy, soft, rewarding sensation on center contact; ball is bullied off the face due to substantial mass behind it.
LOOK: Super-wide sole is well hidden by thick topline; alignment aids on the grip assist in setting up properly.

CONS
Blunt instruments for power, not surgical instruments for precision; short irons don’t check up as quickly as expected.

Designed for: Max game improvement
This integrated set blends three hybrids (4, 5, 6), two transitional hybrids (7, 8) and cavity-back short irons (9, PW, GW). The hybrid long irons utilize “Velocity Slot Technology,” which allows the clubface to flex more for increased ball speeds across the hitting area. The low-profile transitional hybrids offer a lower center of gravity (by 12 percent) than the Idea a7 OS, as well as a thinner face and more perimeter weighting. The short irons have a deep undercut channel to aid mis-hits, a wide cambered sole and a pleasing sound (they’re not hollow) at impact.
