Yeah, try to find a pack that carries the weight low and has a form that fits so that the weight is sort of resting in the small of your back, just above your butt. I commute with an L.L. Bean Escape - and it works perfect for me - even on days when I have to stuff my laptop in with my clothes. If I tried to ride with my laptop bag (backpack) it would not be fun. If you have a good outdoor store near you go try some on.
