What the thread found

• One operator reported that low-frequency vibration occurring with the Superpost extended horizontally on an ARRI Trinity was completely eliminated by using a Post-Extender instead.
• The Post-Extender counterintuitively proved effective despite adding an additional connection point, contrary to expectations that more connections would reduce stiffness.
• The operator recommends keeping at least one Post-Extender on hand and using it for extended post situations rather than telescoping the standard or Superpost.
