Force feed is perfect to ensure reliable play with a pump. Or simply reliable play.
There are many circumstances when a gravity loader simply isn't good enough for pump play. When the gun is angled, or when shooting and running.
If you are going to make the perfect pump hopper I have no doubt it should be forcefeed. It should also be as small as possible and dedicated to pump play, but then you are potentially talking hundreds of thousands of dollars and no reality of making the money back.
