Hmm, with horaries that I've ran recently, I'm domiciled Saturn either in the 11th or conjunct the ascendant, and with Capricorn, over the years I've gotten it with Pluto partile the ascendant, which I find pretty curious - the outers haven't had the wide range of significators that the trad 7 have, but when they make their presence known, I like to take notice. A lot of what it out there on them is pattern recognition and conjecture, but if you're not willing to explore new territory, knowledge will stagnate.
With my sigs, there seems to be a hierarchical system where I get certain planets depending on what is happening in the sky at the time. Whenever Mars is in good celestial state (domicile, exaltation) that seems to be my primary sig. If not, then Saturn is secondary, then Jupiter in third. I get domicile planets as my sig. a lot as well, which echoes what happens in my natal chart. I had a string of charts with either the sig. in 10th or the moon in 10th, and looking back, you could say that there was a lot of career development occurring, even if it wasn't "traditionally" the case.
Your horaries should be different since you're asking about different situations. I remember once I was asking about a drug that I wanted to experiment with, and having no access to it, asked what would be the effect of taking it - I was Mars again, but this time I was combust, in fall and in the 4th house - the chart saying unequivocally that I would get phucked badly by taking it. Still one of the malefics, but the chart was rich in descriptive value.
