I disagree with the above that the 34 would be "too big" for your frame and also that the 34 is that much larger than the 30. It's really not - when they're looked at side by side, you can barely tell the difference between them size-wise.
Where they ARE different is where they fall/hit a person on their body when carried over the shoulder. At your height, the 34 would hit you more against your hip, while the 30 would be higher up under your arm. I personally find that both of them are too bulky to carry directly under the arm, so it almost doesn't matter which one you choose - both of them carry more comfortably when swung back behind your arm, if that makes sense. Since I find the style extremely functional, this little issue doesn't bother me and I love both sizes equally.
I'm sorry I don't have any pics RC - and unfortunately this is one time that I'd really recommend that you might want to try this one on in person. I don't think you'll think it "looks" too big, but the different drop is something to consider.
