20K SuperLite
The 20K SuperLite is a lighter gooseneck-ball fifth-wheel head that drops onto an existing ball for a 20,000-lb tow with no rails required. Easier to handle than the Super 5th and a bit cheaper, with only a slight give in ride smoothness.

21K 5th Wheel Hitch
This 21K head drops onto an existing gooseneck ball, letting you run a fifth wheel off an under-bed gooseneck without rails. Decent build and easy to set in or pull out, though the gooseneck-ball mount transmits more chucking than a dedicated rail or puck setup.
