I wasn't addressing termination, but impedance. Given a minimal mechanical coupling between string and bridge, which I am assuming, sustain is primarily an impedance thing. The mass of the bridge agraffes raises the impedance at the bridge, slowing the assembly's absorption of energy from the string, and increasing sustain. The discussion was on how the agraffe termination steered string excursion in a specific direction that increased sustain and I disagreed, offering that the added mass of the agraffes was the reason for the increased sustain.
