The 70-200mm IS II USM is a great lens, no matter what body you have.

I have owned both the 24-70mm and the 16-35mm II. IMO the 16-35mm II puts out better IQ and is a better lens. The 24-70mm is overdue for an upgrade where as the 16-35mm II is a newer release. There have been rumors of a 24-70mm II release but as with most rumors you do not know when and if they will take place. The only reason I would consider the 24-70mm is if you need that exact range. Otherwise +1 for the 16-35mm II.

There is no fast canon FF on the market right now for sports. Wait a few months till the 1D X is released since budget isn't a factor, it will be FF.
