rick it's subjective, perhaps you could try both and see which you prefer,
due to gravity effect there will be a difference of about 1/2 cone between
large and small cones of the same designation. small cones can tuck in
tighter places like under the belly of a ''full figure'' form, but as
recent posts indicate quite a number of people have difficulty seeing cones
of any size so find your own way with this.
for tracking a fireing using a greater number of cones in sequence, some
folks put a pack of small cones directly in front of a pack of assending
order large cones.
The most personally meaningful and far reaching learning comes from trying
things out there in the unknown. tell us your discoveries.

I think it's less subjective than that, David. My understanding is
that the small cones were formulated by Orton specifically for use in
kiln sitters to bend later than their similarly-numbered larger size.
The metal rod in the kiln sitter that trips when the cone bends
exerts some pressure on the cone and makes it bend more quickly.
The Dawson folks told me that it's more the pressure from the rod
than gravity that will deform the cone in a sitter.
BUT... if someone wanted to use smaller cones as witness cones, and
they didn't mind that they were harder to read, AND that's all they
used so their results would be consistent, AND they didn't mind that
they wouldn't be able to compare their cone numbers with others'...
why not?
My $0.02 (in small coins).
Regards,
Maurice
