by the by,I have a cousin with Libra Sun in 8th house.His Sun is quite visible in his mannerisms and voice(reminds me of Roger Moore,another Libra) and it rules the 6th.
By Hellenic standards shouldnt this be a difficult sun to shine,invisible to the AC.??
His son has also sun in 8th in virgo,and the ualities are more visible than his aquarius AC.

The rising sign is one of the most tender doorways into an individual's psyche. This was where, as a child, they were all wax and impressionable, where they first discovered the need for a mask, and so constructed one.
This is modern psychological astrology and your question is better posted in the General Nativities Forum where it might get some attention. This Forum is for traditional astrology.
