As someone who bought the 4kg hinge, I would like to know whether the new 3.5kg hinges will have improved performance on the “resonance” issue (Explainer: Lid rigidity, hinge force, the CNC Top Cover, and the new 4.0kg Hinge Kit - #2 by A_Fan) versus the 4kg hinges. If so, it may be worth picking them up, even for those of us who already have the stronger 4kg hinges.
