Some films are not sensitive to longer wavelengths at all so something like 900 nm would give you black frames. If you're shooting digital it might be different. I haven't really checked but I think digital sensors are sensitive to longer wavelengths than 720.
All in all I'd say 720 is a safe bet and a good all-rounder, though, yes.
Mine are all with 720nm filters.
