They paid their money, let them take their chances. ;-)

Yep, and they paid in advance.

They use and allow flexible stainless steel braid where the braid will
not interfere with other motions. They usually do not use braid on
things that move during use, only on things that might be moved
occasionally. Where they must maintain the geometry of a bonding strap
or subject it to frequent motion, they use only bronze spring stock.

But consider too, they're an old, 'established' organization with safety
rules that date all the way back to the 1930s. So they may have passed
by newer materials and technologies for what they already know works.
Why spend money on testing for solutions you already have in place?
(unless you don't trust them)

We submitted a request for them to review the characteristics of #301
spring temper stainless, and they were at least receptive. We'll see
tomorrow.
