What is the MPX chassis like?

Is it easy to steer one handed and bump up and down kerbs? Is it easy to get up and down kerbs? Is it heavy to push in rear facing mode?

Big.

It's pretty easy to steer (can't remember doing it one handed but I can't remember having a problem if I did) and easy to get up and down kerbs (I used to bump it up and down 3 flights of stairs so I tested it well ).

It's fine in rear facing mode and that's what I miss most about moving to an umbrella fold - the contact was so much better with ds.
