I've used both the flight suit and the aviator harness. Flight suits are great for taking a bird to someone's home who is not comfortable with a "pooper" in the house!

I prefer the aviator harness but it all comes down to what the bird is comfy with. It may take a while for Schroeder to accept the aviator as it does require slipping the loop over his head. Once I get the aviator fitted to my bird, I loosen it somewhat to remove it but never have to adjust as much as the first time I put it on my bird (if you know what I mean).
I've also tried the feather-tether, which I never use anymore. Darn thing has so many clips and hardware that it always took me forever to figure out how to get the darn thing on!! From what I've read, I don't think I am alone.
