Having pioneered the use of so-called Velocity Slot Technology (VST) in the head of fairway woods in an effort to increase distance, Adams Golf engineers say they have now taken the technology to a new level with the introduction of the Speedline Fast 12 metals. That is a result of what they call Second Generation VST, which utilizes a slot within a slot on both the crown and the sole of the club.
According to Tim Reed, the company’s vice president of research and development, that advance has allowed his technicians to increase Characteristic Time, which reflects how long the ball is on the clubface and how much energy is transferred during impact, by 11 percent over the previous Adams iteration of that metal, the Fast 11. And a 22 percent increase over fairway woods without a slot.
“By placing a slot within a slot, we were able to create a thinner and more flexible structure,” says Reed, “This creates an even hotter face than we had in the first generation of VST. We also have been able to improve launch conditions even more by designing the top slot to flex more than the sole to increase launch angle without increasing spin.”
In addition to increasing CT, he explains, his engineers found the new technology expanded the sweet spot on the face of the Fast 12, which features a satin silver crown and comes standard with the Grafalloy ProLaunch Blue shaft, making it more forgiving.
One fan of the new club is PGA Tour professional Kenny Perry, who says that during his initial test of the Fast 12, his carry distance jumped from 254 yards with his previous 3-wood to 289. He described the Fast 12 as “the hottest 3-wood” he has ever hit and said it made him “feel young again.”
