I'm wondering how the top harness heights compare for these three seats? I'm looking to continue to RF my 33#/40" daughter and the Complete Air did not work for us and I don't think the Radian will fit in our vehicle. I tried a MyRide at the store (we don't have a BRU to try a Momentum) and she was already 1" from the top of the shell, so I know that would be too short for us, but maybe it would give me a point of reference to compare others to. Thanks in advance!
