I have a Zeagle Tech, and my wife has a Zeagle Ranger. We are very happy with them.
We opted out of the backplate route because we travel and dive, therefore lugging around a backplate is a big pain when clearing security. They will always want you to break open your carry on. Also the extra weight is not worth it to us during travel.
My wife is also not a technical diver, and so she has little practical need for a backplate, since she never wears double tanks, so she does not feel like lugging a backplate around.
The Zeagles are modular, and you can take them apart, and roll them up, for travelling. The wing rolls up nicely when disconnected, and the body harness rolls up nicely as well. Both pieces fit nicely into carry-on luggage, or you could stuff them into the corners of your check-in luggage, saving space for you inside the luggage.
