A rucksack is more comfortable than a shoulder bag BUT there is an alternative to both and I have to say I find mine very comfortable indeed. The load is better distributed and it is easy to sling from one side to the other yet still always have top access and you can work without putting the bag down. I find this very useful as sometimes I am standing in a river when making a photograph. It's a Think Tank Sling-O-Matic.
