Hello! I just saw this. I still have the blade but I am using it as a spare. I have DHS PF4-50 forehand and 729 563 mystery 3 medium pips on backhand. I cannot compare it to Butterfly innerforce as I do not have it. Compared to my Donic Original True Carbon inner, the Paladin is faster and feels stiffer. Speed is about the same as my Fan Zhendong ALC.
