Thanks for the reply Macdadtexas.
After reading the blurb on both products it seems the Zephyr's elliptical stylus was used to alleviate the tracing problems with azimuth roll in unipivot arms.
Since the Phantom has the 'magnaglide' stabilisation to prevent azimuth changes, maybe the line contact equipped Aida would provide higher performance for my situation(?).
Perhaps I'll enquire with SoundSmith.
