Not much more I can say to add to the previous obscenities. Just that, all things being equal in material props (E), your stiffness will be proportional to moment of inertia of the cross-section. There are formulas for calculating the curvature according to applied load and its distribution, once you have EI. For comparisons of shanks of similar wood the I is a good indication of stiffness. Now, whether we want them stiff or a bit limp, that's a 'nuther question altogether.
