Happy you like yours. Still not a fan. More is lost than gained, in my opinion, from the single length concept. That being said, and I have stated before, variations of progressions are fine if it works for any individual. Having 3 lengths, for instance, makes a lot more sense and reduces the total distance gap a player will loose with the one length. Our KE4 irons, with their adjustability, can be adjusted to accommodate progression other than the traditional, but probably not to the extreme needed for one length. To answer your question, we will not be doing a single length iron head set. We may be missing out, I understand. I guess time will tell.
