I am not to sure about the absense of off-axis force vectors. Because the long lever arm still is pushed by a circular action.
Furthermore Vienna pistons involve a comparatively high friction area. The high class Vienna valves, that I once tried, had a very spongy fell to them.
Which might account for their low survival rate in all sections of the music business. With the brilliant exemption of the VPO. An even they have no Vieanna valves applicated in their trumpet, trombone, or tuba sections.
