Are there any other Saturn interaspects? I am assuming you're talking about interaspects between two charts, as opposed to a composite chart, because you used the word synastry. If so, are they soft aspects? Any hard aspect involving Saturn and a personal planet(Sun, Moon, Mercury, Venus, or Mars), can be quite difficult to overcome. From what I've seen though, the Sun and/or Venus in hard aspect to Saturn are usually the most difficult. Mars square Saturn often makes the Saturn person feel like the Mars person is "childish." The best thing to do is be aware of what the aspect creates. If you want to give me more information I can help you find other items to counteract it.
