    Just wrapped a Stack Wedge session and tracked every shot with Mevo+. Check out the carry comparisons. Stack Wedge powered by the Stack Radar has obvious limitations, but what a great combo to practice distance control.

    If you enjoy golf, you should have an understanding of Strokes Gained. Here is a short clip from my presentation at Open Forum IX during the 2023 PGA Show in Orlando. I share some simple visuals for understanding strokes gained off-the-tee. Open Forum is known for being the

    It seems that the ruling bodies believe that the average clubhead speed on the PGA Tour is NOT a function of how far the ball currently travels on existing course layouts. Are they under estimating the potential of a small number of the world’s best golfers? Is a 115 mph

    What do you know about the relationship between shaft flex and clubhead speed? Golfers probably spend more time getting fit for the optimal driver shaft flex, than any other club parameter. This makes sense since shaft flex can have a large systematic influence on the launch

    Possible outcomes of suggested golf ball rule. The conforming balls cost $500/dozen. Ball OEMs decide not to design a conforming ball. Ironically, by creating multiple sets of rules, the Rules of Golf governing bodies gradually start to lose relevance.

    Visualization of an actual clubhead trajectory sampled at 5000 fps. Part of a presentation I’m collaborating on with @Ehenrik for #CoachCamp with @AndrewRiceGolf. We’re taking a deep dive on changing attack angle from an impact, ball flight, and golfer repeatability perspective.

    If you've ever considered playing a longer driver, check out this video on the influence of shaft length on driver clubhead speed. Lots of pictures and a tolerable amount of math.

    I’m bummed about the format for the @PGATOUR next year. Cuts add entertainment value. They mean something. Also, my favourite viewing scenario is the 150th ranked player going toe-to-toe with top 10s on Sunday. Less of those now. Might be Majors only for me next year. #newcoke

    Inspiring commitment to continued improvement. @MattFitz94 had a record breaking speed session on Tuesday @playofffinale and smashes a 184 mph drive en route to eagling his final hole on Thursday.

    I don’t drink enough ☕️ to debate @PhilMickelson, but I do have thoughts on non-dominant swings for speed training. There’s a better way to train decel… if that’s what you’re into. Please watch full vid here vimeo.com/sashomackenzie… @TheStackSystem @LukeKerrDineen @peterjkostis

    Pretty cool to see the back of the grip separate from Bryon’s trail hand heading into impact with driver. #clubkinetics
