I sometimes commute on low spoke count wheels.

It hasn't been a problem but if a spoke does break, you may not be able to straighten the rim enough by adjusting the tension on the other spokes to ride home which would be a drag. I recommend you get an emergency spoke replacement.

You can use it to replace a spoke even on the drive side of the rear wheel. They don't take up much room in your seat bag either. It came in handy last Fall on group ride when one of the guys was doing stuff you just shouldn't do on a road bike. He went off into the woods to go over this drop. Suddenly we hear a not so great landing followed by a "ping ping ping ping" and a slew of obscenities.
