John, Congratulations on the new arm. I can't tell from the photo. How are VTA, azimuth and anti skating adjusted? And do you adjust VTA/SRA for different LPs?
I really like the low slung counterweight allowing the weight to be extremely close to the pivot point. I have manipulated the VTF on my SME V-12 to do the same by using a combination of dynamic and static VTF and the right number of extra weights to balance the cartridge. The SME counterweight sled is within a few mm of being as far forward (toward the pivot/bearing) as possible without obstructing movement.
The Centroid weight design is very clever, IMO.
