is there any difference in how these two bags fit over your shoulder?? I have the soufflot and i can put it over my shoulder fine, and was wondering if the bedford would be the same... also..since the zipper for the soufflot goes down to the sides, but the bedford is only at the top, can you open the bedford just as much? does the zipper hurt your hands too? pls let me know! thanks!
