Re: Horary vs. Transits eternality
In my opinion:
-horary and transits of the Moon, Mercury, Venus and Sun would both tend to deal with relatively shorter term "answers"
-transits of Jupiter, Saturn, the Lunar nodes (and the outers) would tend to deal with long term "answers", moreso than horary
-event charts (charts for important events in the relationship, eg, first meeting, first date, first romantic encounter, etc) would reveal more about the eventual development/outcome of the relationship, than either horary or transits.
