Hi Rob,
Thanks for the information -- this was helpful. The ability to disassemble
might be a handy feature. Ease of making fine adjustments in positioning is
an aspect I hadn't thought of. If I go with a quick-release head, I'll
definitely go with the 3413QR/308RC.
Now for the chemistry lesson. (I think I can do that since I'm a chemist.)
I'm hoping that nobody on the list would be more likely to buy a polymeric
component that's described by a salesman as "made of resin" than one which
is described as "made of plastic". "Resins" are cured, hardened,
cross-linked, etc. to form "plastics". Probably more correct to describe
this ball as "made of highly cross-linked space-age super-duper wunderbar
resin", but it's a plastic ball nonetheless. Probably very good plastic as
well -- nothing wrong with that.

Have a nice day,
Bill
