The new Mizuno Pro S-4 irons are here, and I finally got a chance to put them to the test! I break down how they look, feel, and perform, plus whether they might be one of Mizuno’s best new iron releases.
Also on this episode, we check out some seriously interesting prototype putters spotted at the 2026 Simmons Bank Open and talk about two full sets of irons getting reshafted later this week in the Club Junkie workshop. New irons, Tour prototypes, and some serious club building coming up. What more do you need?
