Don't know how old you are, I'm a little older than the 20 something year olds that you see on utube videos with the modeling shots, but I think the 30 speedy or 30B looks like luggage. I'm fairly tall, 5'10", and have the speedyB 25 & I think it looks great as an everyday bag especially if you don't want to carry around a heavy bag! I have a friend that carries a lot of stuff to work, but she uses tote bags and if you need to carry enough that you need a larger bag than the 25 then just buy a neverfull or a tote bag!
