I'm genuinely interested in it, mainly because the tropical whole sign ascendant has worked so well for me on certain things and the vedic system is balanced and makes sense. The Vedas had good ancient knowledge too.
I am willing to test other astrological methods for other things and I am interested in the difference. For example, I think it is possible tropical western placidus could be useful for certain things, tropical whole sign vedic for others, and sidereal vedic for even more things. I want to find out the accurate difference.
Statements such as "a valid astrological theory should work for the entire globe, not just for the temperate climate zone of the northern hemisphere" aren't actually that true either. They are human projections. A valid astrological theory should work because it is tested as working, not because a human wants it to work in a certain way. If it only works in one certain area, then it only works in one certain area. If there are other methods that work in other areas, then they work in other areas. Disregarding either results is a problem here.
Is it really so hard to accept that tropical could work for some things and sidereal for others and to objectively try to test what works best in what specific areas? The idea that there has to be a perfectionistic one-size fits all method for everything on either side is precisely why there is a pointless endless argument around ego and theory and not results.
Personally, so far I have found my whole sign tropical vedic ascendant in the birth chart to make the most sense in both myself and others for very basic general house and sign predictive astrology. However, I do think that placidus or sidereal may work better for certain planetary aspects and nakshatras. I am open to this being different for a range of things such as time, place of birth, current age, other factors due to navamsas etc...
But the main point is to find out what works and why. The earth could be geocentric, heliocentric, sidereal, tropical, and it still won't change if something works or not. Starting off from the position that it does is limiting to finding the best specific methods.
