What would you bring for weeklong trip with air travel

Would you bring Evenflo Maestro or Radian XT.

Which would be better for:
1. lugging through airport (although it will be on the gogo kidz wheels, so it's probably a bit of a wash)
2. fitting through the security xray
3. installing on airplane
4. installing in rental car.

And in case it effects the answers, this is for my middle daughter--she's 3.5. I cant remember her exact measurements, but I believe she's about 36 pounds, 41 inches

Maestro, no question, though I have traveled with the radian and it wasn't too bad, if you have something lighter/easier to install handy I'd definitely use it. And if something happens to it, way cheaper to replace.
