I've made many osage war bows (all laminates, mind you) up to 78" ntn, with no issues of excessive hand shock, stacking, or poor cast. I've tillered them elliptically and round. They're all narrow no more than 1 1/4" at the grip tapering to 3/8" nocks. I try to keep the tips very small and light to improve cast. In fact, an osage bellied multi lam war bow is my favourite type.
