I’ve always wished the TE style would be offered in a progressive set. I never tried the MPC back in its day, but I did own the Golfsmith Tour Cavity Pros … and thought they were pretty close to perfect (mid iron transition never felt quite right - always felt more like a Combo set. I loved the long irons and 9 through lob wedge). I still have a set of 2-LW heads, barely used, lying around in a box somewhere, lol. Anyway, it just seems the TE design would lend itself, fairly easily, to a progressive set.
