I find 20L more than enough for a few days of clothes ... a 13.3" rMBP, mobile, wallet, passport, pens/pencils, deo, facecream, toothbrush and the U-lock ...
and lunch in a tupper.
I've optimised most of life that way ... it's like living in a MUJI.
You haven't used the right messenger bag then. Mine has a side stability strap and it stays put even under full acceleration off of a light with 49:15 gearing. To get to speed on the main road with that gearing I have to start dancing on the pedals right off the bat side to side, and the bag stays put.
