Hun, how often do you get up to Brissy? The store in Coorparoo should have them all in stock so you could try them to see if they are what you want. Otherwise the staff there know the stock really well, so you could even ring them and ask those questions and see what they say.

I think you would usually need two hands with the clip ones, but you might be able to leave the clip done up and step into it - I'm not sure.
