Go ahead. Start a big collection of bags like the rest of us have.
I have yet to find "the" perfect bag, but generally have come to accept that what is perfect for one occasion might not be for another. I have come to enjoy having several bags so I can select the right one for each task.
Lots will use a sling type bag, but it just caused me too much neck pain on one side, so I go full backpack or messenger style bag.
