That is such a tough choice. I have the audra and I love it. I thought about selling it but I just can't let it go b/c I love it too much! I am also 5'2'' and it is not big on me at all.
I just recieved an hh mercer satchel too in black and I love it also. It's different b/c it is not a hobo but the leather is soft and it is so comfortable on the shoulder.
If you want more organization I would go with the satchel, if you're looking for a hobo I say audra but if you can't decide, I would go with both b/c for me they are great additions to my collection!!!
