Titleist VG3 Irons, 6-piece set Fujikura MCI 80S black shafts - Brand: Titleist - Model: VG3 2016 - Shaft: Fujikura MCI 80 S Black Weight Flow - Grips: Golf Pride mcc ALIGN Standard - Club Numbers: 5I 376g, 6I 384g, 7I 394g, 8I 404g, 9I 415g, Pw 430g ▪️From the Titleist website: Precision CNC Milled Deep Undercut The back face is made as thin as possible to improve rebound performance. In addition, the #4 to #7 feature a precision CNC milled deep undercut cavity design, making it easier to get the ball airborne and providing high forgiveness for off-center hits. High Moment of Inertia Head For the #4 to #7, which require higher distance performance and forgiveness for off-center hits, tungsten weights with a high specific gravity are installed on the toe and heel. By controlling the weight distribution for each club number, a stable carry is created. ▪️From the Fujikura website: "MCI Black" was developed by further evolving the "MCT®" technology that combines metal with the shaft. Conventional iron shafts have the same weight regardless of the club number. To unify the feel of swinging from the driver to the wedge, "MCI Black," which has a weight flow for iron shafts, has succeeded in "weight, frequency, and balance flow for each club number." The long irons are easier to swing, and the short irons allow for a more solid swing. Thank you for viewing.
