With Callaway’s new Groove-in-Groove technology they have been able to turn the 16 grooves on the face into 84 contact points; more grooves means more of the balls cover going into those grooves at impact, this in turn gives you more spin and control of your golf ball.
Callaway’s Groove-in-Groove technology comprises of three raised micro-ridges along the length of the hitting area. Between these grooves are micro-grooves that help grab the ball’s cover to increase spin rate which, according to Callaway, can impart a 1000 more RPM on full shots. They have also introduced an extra ‘Nip-It’ groove near the leading edge helping enhance spin on miss hit or thinned shots.
As with all wedge systems now the CG is progressive throughout. From 46° to 64° Callaway use a system of four circular weight ports which allows the CG to be positioned progressively upwards so they are deeper in the higher lofted heads giving you a solid feel on each shot.
The lower lofts from 46° to 52° use Callaway's 20D grooves that are narrower and thinner, helping to impart maximum spin on full shots, while the higher lofts from 54° to 64° have the wider 5D grooves that impact more grip on those shorter swings around the green.
There are 21 loft-bounce combinations and 4 different grinds C, S, W and New X each come with generous camber from heel to toe for smooth turf interaction and solid feel.
I loved the rounded style of the head shape which sits perfectly at address, it’s a classic tear drop design based on the Mack Daddy Tour Grind shape, but I also felt it gave me a larger hitting area, which also inspired confidence around the green.
I tested the MD4 in both Switzerland and Canada in various climates. I really enjoyed playing with them and was amazed at the amount of spin I was putting on the ball, especially on full shots into the green.
As most of you know I always say amateur golfers should have at least 3-wedges in their bags as it is where we can gain the most shots; I would have no hesitation in recommending the new Callaway Mack Daddy 4 wedges to you, make sure you get a couple in your hands before you make your final purchase. You will be glad you did.
