Professionals - with a few exceptions - always use the deadcat indoors and outdoors. Plus, a moving mic/blimp can create it's own "wind" if you have to move it even moderately quickly. It's also practical; you set up exactly the same way every single time. Plus, you are always ready for anything; what are you going to do, stop the entire production so you can put a deadcat on your blimp when a mild breeze comes up? That may be okay on a low/no/mini/micro budget shoot, but when the shoot cost is $10,000 an hour that three minutes to wrestle the deadcat onto the blimp costs the production $500.
Again, why didn't you ask over on Jeff Wexlers forum?
