The existence of these dips and a fortiori their position is found to be rather model-dependent: present in all eikonalized models including Pomeron, Odderon and secondary Reggeons they disappear when an additional large- t term is added (as sometimes advocated).7 pages (LaTeX), 1 figure (eps), submitted to Physics Letter BHigh Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
