Except for the formals, I would never us a prime lens for shooting a wedding. While "zooming with your feet" sound like a good alternative to a good zoom lens, you will miss more shots and cause more disruption while you scoot around trying to get the shot you want.
My 2 lenses for shooting a wedding (with FX bodies) are the 24-120 f/4 VR and 70-200 f/2.8 VR. During the ceremony, I have each mounted on a body. There is barely enough time to switch bodies, much less mount a different lens or run up and down the isle chasing the wedding party.
The reception poses entirely different problems with space constraints and where the action is happening at that instant, compared to where you are or want to be.
Sorry to all you prime aficionados, but a modern wedding isn't the place for them. I have not seen one pro wedding photographer in recent years using anything but zooms, event for formals.
