But against that a three cross wheel is substantially springier than a
radial.

I'd like to see some backup for this, please.

Assuming you mean what is commonly meant by "springier" and
"substantially" - i.e deflection per unit force

Yup...

and a difference of, say,

Probably.

Take a radial and a three cross and bounce 'em off the workshop floor,
and you'll see what I mean.
