okay girls. i need your help. i'm so confused. although i really love the cabas piano and it's classic look, the poppincourt haut seems like the perfect size for me. but the cabas isn't that much bigger than the PH, is it? i dunno. i'm 4'11"...that's short. so i can't carry too big of a bag. i have a 2 yr. old son and another on the way so i need a roomy bag to carry all my things along with some of theirs. what do you guys think?
