Dan has delivered. The arm parts arrived yesterday and first testing was today and the improvements are significant.

The most noticeable improvement has been at the shock absorber - it’s now doing its job. Previously, with the shock seg at 40psi, at rest the telltale on the shock indicated no sag. Now with the new arm I’m running 40psi with 5mm of sag. I can now move the arm through its full range of movement - full shock travel - without fear of anything breaking.

Toward the end, using the 3D printed parts and having had a few parts break, I’d reverted to not using my short arm side when riding. Subconsciously, I had stopped using my short arm. This is noticeably in the video of my emergency stop practice runs.
