Why use a manifold?

Taken to the extreme you mount the valve directly to the port on the side of the cylinder that needs the most speed. Run supply tubing directly back to the working pressure regulator locating the component for the shortest runs and bends possible. This will not take you from worst to first, but might help when you are battling your arch rival on Einstein for the fraction of advantage. (Of which we have not have had that pleasure yet)
