So, spent three hours at Golftec last week.
All the data (and my own personal feel and aesthetic proclivities) landed on the new Minzuno JPX 825 Pros. Shafts correct length, grip, angles, offsets etc customized.
Custom shafts - KBS c-tapers:

Holy moley, the shafts and feel is amazing. Side spin nil, was hitting my old 7 iron average of 158 carry and these are at 179 carry with 15 yards better accuracy. Lower ball flight (I tend to cast, pinch it and send the ball soaring) but much longer plateau.
Going to dedicate myself this year. Had a great experience at Golftec. Would recommend.
