Found this relatively elegant construction method toward the end of the week which beat three personal paretos, including two  with higher arm counts. One hex-arm is used to simultaneously deliver two quicksilver to the bonder, pivot the tringle intermediary, and deliver one quicksilver for projection. After completing this solve, making slight adjustments to the core idea ultimately produced five paretos for the middle of the curve. Replacing one or both of the multi-arms with single arms gives decent cycle counts for 70G and 80G, while adding a third arm to attach the final silver cuts the period by 3 or 4, saving 18 to 24 cycles.
