Yes I do think that we are on our way to the truth by using the sidereal zodiac. It counts for Earth's precession and is a much closer match to the stars than is the tropical.
Actually a point about the exaltations, Edgar Cayce did use them - it seems to have been one of his most important points on astrology. To find the most exalted planet in one's chart.
Where did Cayce say that a planets importance should be measured by its corresponding exalted sign?
Cayce talked about the importance of planets in terms of where their soul travelled in past lives and which ones are involved in their karmic path...
From reading 1895-1
"
Hence as these records or interpretations are given, it is the desire to give the entity a premise, and ideal, that it may answer to that search from within as to how to make this experience more worth while in this particular sojourn.
13.Then as we find, the experiences of the entity in the earth become an influence just as the environs in any one experience, just as it is true that what ye think ye become, - just as what ye consume for the physical produces such experience in thy physical and mental life as related to the ideals, whether known or still latent.
14.Also we find that the experiences of the entity in the interims of planetary sojourns between the earthly manifestations become the innate mental urges, that may or may not at times be a part of the day dreaming, or the though and meditation of the inmost self.
15.Hence we find astrological aspects and influence in the experience, but rather because of the entity's sojourn in the environ than because of a certain star, constellation or even zodiacal sign being in such and such a position at the time of birth.
16.Know that man - as has been expressed - was given dominion over all, and in the understanding of same may use all of the laws as pertaining to same for his benefit.
17.In the application of same as a benefit, - if it is for self-indulgence or self-expression alone, it loses its own individuality in the personality of that sought or desired; and thus the very knowledge may be used as a stumbling-stone. But if each experience is as a manifestation to the glory of a creative or heavenly force, or that which is continual thus the judgements being drawn from an ideal that is spiritual in its concept, then there is the greater growth, the greater harmony - for there becomes an at-onement with the influences about same."
