I see that in the interests of achieving ever more confusion, VPI has come up with still more tonearm variants since I last visited their website (Mike once told me they have 7 different counterweights for the arm I have, an "original" 10.5i). From what I can tell, though, the OP was in fact referring to the 3D printer armtube or armwand or whatever it's called, not the one Brf cites.
But I could be wrong.
They do remain consistent (see their FAQ) in steadfastly arguing against the use of anti-skating devices, even while now equipping their arms with such devices. I happen to agree with the argument and don't use the device :-)
