GolfWRX Launch Report: 2023 Srixon ZX5 Mk II, ZX7 Mk II irons, Z-Forged irons

What you need to know: PureFrame and MainFrame are the two most important terms in regards to the 2023 Srixon ZX Mk II family of irons. The players iron ZX7 Mk II features PureFrame: an 80-percent thicker portion of 1020 carbon steel forged behind the sweet spot in the body of the iron for soft-yet-solid-feeling impact. Z-Forged has PureFrame as well. The rest of the lineup features second-generation MainFrame technology — a variable thickness pattern of grooves, channels, and cavities carefully milled into the back of the clubface for maximum ball speed-boosting flex and greater forgiveness.

What’s new, key technology
MainFrame v2: Developed with an Automated Intelligence process, flex-maximizing variable thickness pattern of grooves, channels, and cavities carefully milled into the backside of ZX4, ZX5, and ZX Mk II Utility Iron faces for high ball speeds.
Not only does MainFrame boost COR, but it also repositions mass away from the face and into the toe and sole for a lower CG for easier launch, more consistency, and forgiveness.
PureFrame: Reducing unwanted vibrations at impact, PureFrame enhances feel in ZX7 Mk II irons. The 80-percent thicker portion of 1020 carbon steel is strategically placed behind each iron’s sweet spot.
Tour V.T. Sole: Proprietary sole widths, bounce angles, and notches in the heel and toe of the club aid clean contact from a variety of lies.
Progressive Grooves: Laser milling between each groove for enhanced friction. 3i-7i feature wide grooves. The 8i-AW have deeper, closer set grooves that cut through grass and debris to enhanced spin on approach shots.
Forged Multi-Piece Construction: ZX Mk II Utility is equipped with a forged SUP10 face for maximum face-flexing at impact. A forged 1020 carbon steel body offers softer feel thanks to vibration dampening.
Also notable: New for Mk II, every ZX Iron model now features the same topline thickness, so uniform combo sets are a possibility.

What Srixon says
“The technologies driving the exceptional performance of the ZX Mk II Irons are really exciting to launch and get into golfer’s hands,” said Brian Schielke, General Manager of Srixon. “Longer distances, improved feel, more control, and greater consistency are seen throughout each new iron set, and they provide a seamless transition for building a combo set.”
“While we’ve improved these irons in so many ways over the first generation of ZX Irons, we’ve also kept the sleek looks, pure feel, and core DNA of Srixon Irons that golfers have come to expect,” Schielke said.

Adam Scott makes 3 more big changes to his equipment setup at the Memorial

If you thought Adam Scott was slowing down on the equipment changes, you’d be wrong.
GolfWRX got the first look at the retail version of Adam Scott’s Miura AS-1 irons back at The 2023 Players Championship, but it wasn’t until this week at the 2023 Memorial Tournament that he actually put the new irons in the bag. He was previously using the original Miura prototype heads that, coincidentially, he first put into play at last year’s 2022 Memorial event. In exactly a year’s time, Scott replaced those prototype heads with the Miura AS-1 irons that were recently made available to the public.
This week, we also got an in-hand look at Scott’s new Srixon ZX Mk II driving iron, which he’s now equipping with a True Temper Dynamic Gold Tour Issue X100 shaft.
Additionally, Getty Images spotted Scott with a new TaylorMade BRNR Mini driver in the bag this week.
According to TaylorMade, Scott is using a Stealth 2 Plus driver in combination with a BRNR Mini this week, and he’s currently leading Strokes Gained: Off the Tee after the first round of the Memorial, where he shot a 2-under 70.
Scott’s Stealth 2 Plus and BRNR Mini specs and launch numbers
Head: TaylorMade Stealth 2 Plus (9 degrees, with 10 degrees of actual loft)
Shaft: Fujikura Ventus TR Blue 7X
Length: 45 and 1/8 inches CUT (tipped 1 inch)
Weights: 19g back, 15g front
Swingweight: D3.5
Stealth 2 Plus launch conditions: 11.5° degrees launch at 2400 spin, 305 carry, 320+ total, 181 ball speed
Head: TaylorMade BRNR Mini (13.5 degrees, with 13 degrees of actual loft)
Shaft: Fujikura Ventus TR Blue 7X (tipped 1 inch)
Length: 44 inches
Weights: 13g back 5g front
Swingweight: D3
Launch Conditions: 11 degrees at 2800 spin, 282 carry, 305 total, 173 ball speed
“The BRNR Mini driver went into the bag for Adam this week because of the golf course and the distance gap between his driver and 4-wood,” said Adrian Rietveld, TaylorMade Senior Tour Manager, according to TaylorMade. “At Muirfield, drivers run out and the gapping with his 4-wood left him too far behind. As he told us during testing, with BRNR Mini, he can play the golf course instead of the golf course playing him.”
The Adam Scott equipment-centric weekly reality show continues on, and it’s appointment television at this point. Check out what the GolfWRX Forum members are saying about Scott’s latest switches in our forums.
