As a guideline for forthcoming experiments, we focus the attention on the role of the proton's spin polarizabilities and investigate the most favorable conditions to extract them with a minimum of model dependence. We conclude that a complete separation of the four spin polarizabilities is possible, at photon energies between threshold and the $Δ(1232)$ region, provided one can achieve polarization measurements with an accuracy of a few percent.26 pages, 7 figures;High Energy Physics - Phenomenologytext
