Kind of a hard question to answer as the primary need for the lens was not specified. Given the large selections of lenses and bodies you already have, I would strongly suggest going for a decent tele prime. Indoor events could use a 200mm f/2 or the 300mm f/2.8 II. You can add TC's to them for different lengths. These are suggested as price was not given as primary issue. Since you have so many camera bodies, you don't really need the functionality of the zooms as much as a person with only one body to work with. My 2 cents at least.
