Kent, The actions for the two pianos are similar when out of the piano but one can feel the extra weight from the damper springs on the older B's when the action is back in. Your response has given me some encouragement to give the springs a try on one of the newer B's. I currently have one of them in the shop for a Stanwood modification so this might just be the right time! One question, do you modify the weight of the underlever when adding springs? I want to say there is a weight difference on the underlevers between the old and new but I will not know until I return to the shop on Monday. I am installing wippen support springs so I will watch out for the "let-off bump."
