The AVA-response of VTI-models for AVO-Classes 1 to 4 and two special cases is computed utilizing plane-wave reflection coefficients and the Weyl-integral. It is found that below 30° of angle, in most cases, the spherical VTI-response departs more from an isotropic plane-wave comparison than isotropic spherical responses. Depth dependence of isotropic spherical responses is strongest near critical angles, exactly where important information resides. VTI-type anisotropy shifts this point of maximum sensitivity towards larger angles.
