Wilfried, a lot of observing opportunities in this Taurus list, though for someone in my position - south of the equator - Taurus is now heading into the west early in the night, so the list will be more useful late this year when it returns to the evening sky for more of the night.
One matter to be noted - you need to eliminate doubles with K-band (infra-red) magnitudes - the KOH and BOV pairs have 'K' in the notes column, indicating IR magnitudes; there could be others. Taurus has been a happy hunting ground for IR studies which have thrown up IR doubles as part of these studies, but they're not visible to the eye.
Regarding the very dim pairs - these, as I've suggested before, may be a test of observer eyesight and dark adaptation as well as light pollution. I'm planning to try some of those you listed in Eridanus, rather than Taurus, because it's still accessible from my location, if the weather improves here.
