The Ultras use the same amount of power as an incandescent but the supers use about 25%.

True, but that isn't the only reason to get them. It just makes the expense easier to swallow.

It was. But the video gives a good answer for a pin with LEDs and without. Another reason to do this is you can put more pins on one electrical circuit before you run the risk of tripping the breaker. This can be a big deal for those with large collections or old houses.

The non-ghosting CTs are the same as the supers. Should be called non-ghosting supers IMO. And they work as advertised.
If you have a B/W with a lot of ghosting inserts I would have a new patched ROM installed.
