Nike’s new golf balls have larger, softer resin cores

Published

on

In 2012, Nike released a new line of golf balls called 20XI that featured a new lightweight core material called RZN (resin). According to Nike, the lightweight resin cores moved more weight to the perimeter of the ball, increasing MOI to make the balls more stable in the wind. The problem was, the golf balls spun too much on iron shots, causing control problems that negated the ball’s higher MOI.

Rock Ishii, director of product development for Nike Golf, said that the company has solved that problem with its 2013 20XI golf balls. Like last year’s models, the new balls have four layers and a urethane cover. But the new models feature a construction with a larger, lower-compression RZN cores that decreases iron spin and allows for even more weight to be moved to the outside of the ball for an even higher MOI.

According to Ishii, one of the main advantages of the 20XI ball is that its high-MOI construction causes less spin decay after it reaches its apex. This means that the 20XI will to spin more consistently than lower MOI golf balls, which will help stabilize their flight during the critical period between apex and landing.

The new 20XI golf balls are available in two models — the 20XI and 20XI X. The difference between two is that the 20XI X has a cover that is six compression points firmer than the 20XI. This will make the 20XI X spin less than the 20XI from driver to wedge, making it a better option for certain golfers with high swing speeds. The street price of both balls is around $46.

Along with the 2013 models of the 20XI, Nike has also released its One RZN golf balls, which offer a lower price point that the 20XI golf balls.

The One RZN balls feature a RZN core and have a compression of about 60 — 20 points softer than the 20XI golf balls. That makes them a good choice for golfers with slow swing speed. The One RZN balls are available in two models — One RZN  and One RZN X — and will retail for around $30.

Like most non-premium golf balls, the One RZN balls have surlyn covers that producs less spin around the greens than balls with urethane covers. Watch the video interview below with Rock Ishii and Zak Kozuchowski for more information on the One RZN balls.

    Less side spin is good for a 12 handicapper. But the amount of total spin they need is dependent on their launch conditions and preferences.

    Players with slow swing speeds can benefit from more spin because it keeps the ball in the air longer for more carry. Players who slice and hook the ball like low spinning balls because the don’t slice and hook as much.

    So Zak, RE: “This will make the 20XI X spin less than the 20XI from driver to wedge, making it a better option for certain golfers with high swing speeds. ” The 20xi ball would be better for a player with a driver swing speed of 92? But isn’t spinning less a good thing for a 12 handicapper?

    Thanks

The hottest blade irons in golf right now

Published

on

As we’ve written before, the decision to put a new driver in the bag is usually obvious. Better numbers at testing, perceptibly longer distance, and as long as your bank account allows, you have your new gamer.

The iron switch, however, is a trickier beast. Comfort with the variety of shots one needs to hit is key. Confidence from one’s long irons through the higher lofts is critical. Thus, even the greatest enthusiasm for a new iron release isn’t always followed by a mass exodus to gaming said irons. This is doubly true at the professional level, where the tools are critical to a player’s livelihood.

That said, the combination of forum chatter, GolfWRX member enthusiasm, and what we’re spotting in our WITB photos from tour stops are a reliable indicator of the hottest irons in the game.

And judging by the response to our recent Instagram post, we’re confident that these four models are the hottest blade irons in golf right now.

Callaway Apex MB

Buzz built steadily for the Apex MB iron when we first spotted them in Tour players’ bags at the beginning of 2017. The irons are the product of direct feedback from the company’s Tour staffers, according to Luke Williams, Director of Product and Brand Management at Callaway. Forged from 1025 Carbon Steel, these irons have the shortest blade lengths, the thinnest soles and the smallest overall heads in the vast line of Callaway irons. They’re designed for maximum workability, and for tour-desired turf interaction.

Mizuno MP-18

The pioneers of Grain-Flow Forging, Mizuno went back to its roots with the MP-18 iron model. A throwback to the great muscle backs in the company’s history, Mizuno was shooting for the look of an iron that could have been forged a century ago. Shorter blade length, cambered top line, sharp, compact wedges, all combined with the most minimal badging make the MP-18 an instant classic that set the GolfWRX forums afire.

TaylorMade P730

TaylorMade’s P730, particularly in its prototype incarnations, made quite a splash on the PGA Tour. Building on the heritage of the TP-MB irons, P730 was developed in collaboration with the very best players in the world. The 1025 carbon steel irons irons feature a smaller profile and crisper lines than the MB series irons. The combination of the clean look and a deep rear groove have players drooling. Discussing working with Dustin Johnson and Justin Rose to design the P730, TM’s Senior Director of Irons, Tomo Bystedt said, “What these players need is a very low-inertia club that they can [manipulate] easily, almost like a surgeon’s scalpel.” Behold the scalpel.

Titleist 718 MB

“For the purist there is no substitute for a one-piece, muscle back iron. The 718 MB is the modern choice for those desiring a traditional forged look and feel,” says Titleist in the 718 MB marketing materials.

It’s hard to argue with that statement from the “appearance of a classic forged iron” standpoint. Purists appreciate that the 718 MB maintains Titleist’s traditional lofts (the 6-iron is 31 degrees, the pitching-wedge is 47 degrees), thin top-line, minimal offset, and limited badging. In short, if it ain’t broke…
