Ahoy Captain.... right now, the entire arm is gone, awaiting the 3D. I imagine the tower will be (at least) similar to the 10.5 but for cosmetic changes. The tower works so well, I can't see VPI changing it for something else. The real pain in the neck is the anti-skate. If you use it, the arm tube is not readily changed since the whole arm has to be adjusted again. I haven't been using it on the 10.5i, and Harry is not a proponent of anti-skate, but I would like to have all options available. I understand the anti-skate gizmo is included with the 3D...we'll see.
