I don’t think I’ve heard of anyone running it on a straight tracker.

is that dealer located near you Henry ?
I run a custom ET 2.5 straight tracker. It has patents. Mine is a custom built unit from Bruce Thigpen. It also has this special joint part that we call the Gooseneck, that I was able to acquire from your neighbor New Zealand, courtesy of Richard Krebs. Also a custom ET2 straight tracker user.
fwiw
My tonearm has been, with the exchange of appropriate armwands and leaf springs for compliance tuning, able to handle everything from a lightweight Sonus Blue Gold to the XV1. So not worried about the Decca. As long as the records off-center is decent, and the air really good, the arm can handle anything mounted to it.
