You are right about the design of the straps which make it easier to place on the opposite shoulder.

The Eddie Bauer bag I have has the straight style shoulder straps, but I wear it on my left shoulder with the bag at my right side. Your straps will support a bag better in such a position, but for the $3.99 US I paid at the local Goodwill store, I can't complain.
