Fender Jazzmaster Jaguar trem unit video

I skipped through the video a lot due to the same issues previously noted.

The point of the video seemed to be "thin is bad thick is good". Did I miss other nuances due to the distractions?

Just because the steel is thicker, doesn't mean it's "higher quality"...

Did the knife edge hinge points move around into better or worse positions?
Did they do a better job shearing the steel to get a more uniform fulcrum edge?
Is the thin metal so thin it is flexing during operation?
Are there other geometrical variations that matter?
Why is thicker steel good and lighter weight yet sufficiently strong bad?
Was the thinner steel bridge bent to the same forms as the thick model such that gaps, slop, and rattles became worse? Or did they adjust the die sets to match the materials?
What is the compression strength of the springs? Disassemble and use a common weight and measure deflection mm of the spring -- that will reveal if the spring rates of the two/three springs are significantly different. Perhaps the spring wire diameters are significantly different to reveal a problem in spring rates (presumably to not return to correct tuning or yield unstable tuning with weaker springs).

Those are the quick questions to get at the true differences, if any.
