When Costco puts in a hitting bay with Trackman and hires club fitters and has shaft options for me to test, then I’m interested. Until then, well…
I’d be shocked if these irons weren’t high quality, though, like everything that Costco puts the Kirkland name on. I just can’t imagine why, in 2023, I’d buy a golf club with some sort of a fitting/test process. But that’s just me.
