I’ve had a VPI Classic SE with 10” 3D uni-pivot arm for the past 8 years, no issues. I don’t think it’s any more difficult to set up with a cartridge than other arms and it’s as stable as any gimbal arm playing on the record. It’s totally adjustable including azimuth, some arms are not. It’s also an amazing tracker, in all this time it has never skipped or malfunctioned—pretty amazing.
