I see no advantage in using something like polycarbonate. Metals are proven.
If is works, don't break it. Metals usually have more durability from repeated
use or movement.

I think plastic got a very bad, but deservedly so rap in its first generation
of being used in cameras. The polycarbonate materials used today are very tough
and resilient. I still think its a very bad idea to use it in a lens mount,
though, because of the nature of it to flex, and/or tear loose from where it is
finally mounted to metal. The polycarbonate itself is not the problem, but the
meeting place with metal is.

Brass is far more malleable that stainless, will usually deform/bend/dent
under stress. Some of the harder alloys of stainless will fracture/crack
under the stress of an impact (being dropped). Neither is a good outcome,
but sometimes the brass part can be 're-shaped' back into a useable form,
whereas the stainless part is destroyed. Plastic tends to have the
unmalleable characteristic of the stainless, and likewise exhibits the same
tendency to fracture/crack... albeit at a far lower force. Remember our
wonderful thread awhile back about beating anybody's 'wonderbrick dejour' to
pieces with an OM-4T body.... Ah, what a lovely mental image that
conjures......
