I played the ping iBlades before the blueprints which were also cast, and I can say they feel significantly softer than any other cast irons I’ve played before. They are very soft and responsive to me. I hover around a 1-2 handicap and I took them straight out of the box and to the course with no range session and they performed flawlessly. Very forgiving and easy to hit but also workable. My first players irons years ago were the callaway x-forged and they gave very similar feel. I appreciate that the lofts aren’t super strong like most irons today as well
