Neat article! While I don't have single length now, my initial reaction to the concept when I first heard about it was, "yep, that makes a lot of sense. Variable shaft lengths are pretty stupid."
They cite that if you were inventing the game today, you would not make every club a different length. If you did, you'd sure as shit MOI/TLT match them so you could play competently with fewer variables in the swing. Single Length is a lot simpler than MOI/TLT matching.
I'm in, but my JPX 850 forged are so pretty 🙁
Next set I buy will be single length. I suspect these "obstacles" of distance gapping will be resolved within the next year or so, as they seem fairly minor.
