Small rack for a route that you are repeating as opposed to a FA would be 4 hexes 6 nuts and 3-4 tricams plus 6 to 8 shoulder-length slings with 2 biners per sling.  Cams are too heavy to take on a "small" rack.  if the climb is hard enough you can't be bothered to spend the extra time finding a good hex placement, then don't take a small rack. My dos centavos.
