Jim, sorry to hear about your misfortune and unnecessary expense. I do hope that all is OK now. I have always carried my 70/200 lens plus camera body by the tripod foot/bracket but will stop that practice immediately. I was very fortunate a year or two ago. I was photographing animals from a hide with my D3 and 200/400mm f4 VR when a Fish Eagle started hunting in the dam. I wanted to fit a TC and placed the lens on the shelf. It dropped about 1,5 meters to the floor, fortunately striking my foot on the way down. Despite many anxious moments it suffered no damage although my foot was very bruised and painful for some time.
