Just for the record, I am not a fan of the second pivot. Assuming the compliance of your cartridge is within reasonable bounds it should not be necessary. Single point designs have proven their value over the years.
The VPI second pivot is a Rube Goldberg design (contraption, really) intended IMO to appease those uncomfortable with the wobble-while-handling of the single pivot arm. I believe VPI offered it as a marketing maneuver just as they offered the anti-skate device after years of saying, not only that it was not necessary but, that it made the sound worse.
There are real two point designs out there that are valuable, but not VPI's IMO.
So my comments above apply to single point use. But YMMV.
