Callaway has revealed details on its new Mack Daddy 4 wedge, designed in conjunction with Roger Cleveland and input from Tour pros.
Engineered to offer optimum spin through the lofts, the grooves are saw-cut and horizontal milled to precise settings.7
Cleveland said: “MD4 sets a new and higher standard in performance and appearance. Shape, feel, spin, control, versatility, finish and detailing have all been elevated to the highest level we’ve ever achieved.”
Lower lofts (52 degrees and below) have a 20D groove for consitent spin on full shots while high lofts (54 degrees and above) feature an aggresive 5D groove for maximum control.
The 16-groove set-up features a “Nip-It” groove near the leading edge for extra control on short shots.
The Micro-Positive surface roughness, which is milled into parts of the face, has three raise micro ridges extending across the face, with micro-grooves between ridges for extra spin on all shots.
Callaway say the grooves create 84 contact points to help grab the cover to impart spin.
The shape of the wedge is more compact in 2018, with a straighter leading edge, tighter leading edge radius and more offset compared to the Mack Daddy 3.3
The tighter radius is designed to help players make better contact on clean lies.
“Tour pros like only a subtle amount of leading-edge radius,” said Cleveland. “In the Mack Daddy 4 we gave them enough to make a performance difference while still pleasing the eye.”
Soft 8620 carbon steel is employed, with four weight ports and milled aluminium medallions allows Callaway to position CG progressively higher in the head as loft increases for improved feel.
Callaway say the choice of shaft, grip and the bounce and grind options enhance feel as well.
There is one new grind offered in the Mack Daddy 4 - the X grind
X grind: The newest grind features a narrow, high-bounce crescent sole, with the low point near the front. Made for moderate-to-steep attack angles and medium-to- soft course conditions. 12 degrees of bounce.
C Grind: Increased relief, especially at the heel, making it easier to play shots with the face open. Ideal for medium-to-shallow attack angles and/or firm course conditions. 8 degrees of bounce.
S Grind: Medium-width sole with slight chamfer at the back and moderate heel relief to keep the leading edge low through impact, promoting solid contact on open-faced shots. 10 degrees of bounce.
W Grind: Sole is wider at the center and toe and narrower at the heel, with moderate heel relief and generous front-to-back camber. That prevents digging without increasing bounce, and keeps the leading edge close to the turf at impact. Great for open-faced shots. More versatile than our previous W Grind. 12 degrees of bounce.
