VPI 3D arm


Is the VPI 3D arm considered a high-mass arm?
Thanks.

All well and good but nobody answered the OPS question. That is a thread hijack folks.
@drewmb1 , I am using two different metal Classic arms in lew of the 3D arm that came on my Prime. One of the arms are off a Classic 1 and the other from a Classic 3 with no mods, these arms are interchangeable, I believe the problem is with some of the older 10 inch arms.
Yes, you are correct.  It's actually that the damping well interferes with the 3d arm.
I am excited about using my 3d arm though, presuming VPI can get the owner to approve a shipping ticket...........
