It's proven over time that the new tech is helping to lower scores, but those advancements don't come with every new club/ball variation, as you know. That's just good marketing.
Point being, depending on how old your clubs are, you may surprise yourself just how much better you can get. The new drivers are insanely good at reducing spin and allowing for maximum forgiveness.
Just a few years ago, I went to a driver fitting at a local course. For years, I played with a Titleist 975J driver (2001-ish release)....so you're talking almost 20 years old at the time of the fitting. Same exact swing, but tested over various brands and shafts, I legit gained 25-50 yards across all drivers. I hit the new (at the time) Ping and Titleist drivers 50+ yards further and with tighter dispersion. It was insane. I bought the Titleist right then and there (love the brand, the sound, the feel).
*With that said, to anyone else reading, I'll still advocate for lessons over new clubs any day.
