We tested: 5-PW with Ping TFC 149i graphite shaft; 5-PW with Ping AWT steel shaft
Key Technologies: A lightweight titanium face insert moves 27 grams to the perimeter and sole to boost forgiveness. The broad sole lowers the center of gravity (for higher shots) while internal weighting stabilizes the clubhead through impact. Comes with the option of up to four hybrids (3-6).
OUR TESTERS SAY: Extremely forgiving, high-trajectory irons that can reduce your tendency to slice.
PLAYABILITY: Cuts through the rough well and performs nicely from a variety of lies; gentle draws and fades are possible, but better suited for high, straight shots.
ACCURACY/FORGIVENESS: Very good spin correction across the face on mis-hits, particularly on potential slices; consistently straight on all types of contact.
DISTANCE CONTROL: Not overwhelmingly long, but length is consistent throughout the set.
FEEL: Provides subtle feedback on mis-hits but is never unpleasant; crisp sensation when struck in the middle of the face; outstanding stability on all shots.
LOOK: At address, the sizable back cavity and large sole are well hidden; classic Ping style that many testers like.
Some testers feel its trajectory is higher than optimal; a few testers find that overall distance isn't quite as long as they'd like.
From Sports Illustrated Golf+ (February 7, 2011)
A multimetal iron design combines a large, lightweight titanium face with a 17-4 stainless-steel body to increase forgiveness and improve launch conditions. Weight saved from the titanium face is allocated to the sole and perimeter to achieve more accuracy and higher ball flights. The K15 hybrids are available in 3H, 4H, 5H and 6H. They rely on an extremely high moment of inertia and a patent-pending feature that creates lower-spinning, higher-launching shots that fly longer and straighter.
From Golf Magazine (December 2010)
It's for: Max game-improvement players
K15 irons enable you to customize sticks for optimum performance. Construct your own set makeup from a choice of nine irons (5-iron through lob wedge) and four hybrids (3h to 6h). Perimeter-weighted, multi-material irons (stainless steel body and lightweight titanium clubface) have loads of perimeter weighting to boost ball flight, and forgiveness. The hybrids are crafted to produce high-launch, low-spin shots through increased MOI and "optimal" CG position.
