I have an incomplete set and I’m hitting these far better than my new Ping i210 irons.
The Kinetic CER does go back to 1989. Unfortunately, we do not have any of those available. No wonder you hit them better since the playability factor on the Kinetic II CER was 898 (Ultra Game Improvement) and the Ping I210 is 338 (Classic). You might look at the KE4 Tour or the KE4 S irons we cuurrently have. They are both Ultra Game Improvement irons and should play as well as the old Kinetic II CER.
