The advantage to the corotor is setting skew per polarity per sat which you can not do with a lnbf. Setting cost aside I would go with a corotorII with C and Ku lnb's. Second choice would be the standard Ku BSC unit that does both c and Ku. The universal offering does not play well with a 4DTV receiver. As to all the same. In concept yes. As long as you are working with items designed for a big dish they mount with a scalar ring. These rings have multiple mounting holes to fit any configuration I have seen. The corotor or lnbf then mounts inside the scalar ring and is held with set screws. Hope that helps but if not clear or only created more questions feel free to ask away.
