Danny, I know exactly what you mean about the "Nose Over" technique employed by Stukas, and very unpleasant it must have been been too. Starting an attack with a negative g bunt, only to end it with a large positive g pull out! But there again I speak merely as a truckie; straight and level only and tea on the hour, every hour!
However it would seem that they also employed the wing over technique, peeling off in formation to begin their dive. This excerpt from "Die Deutsche Wochenschau", a sort of teutonic Pathe News, shows them doing just that during the later Russian Campaign. Possibly they altered their own tactics in the light of operational experience? I must say I prefer the Bob Danvers-Walker delivery to the loud ranting in this clip:
