Using Vedic with Tropical Zodiac??

1
Hi, I.m come to Vedic late in life, after over 30 years using Western astrology. However I am amazed to find that there is a school of thought that wants to mix up tropical signs and still use dasa . They are totally out in my life...60 years so lots events to verify!!
I admire EWilhelm, but can others really verify this system??
For me it's about the ascendant. I struggled for years to apply a Gemini Asc to myself, but Vedic finally made 100percent sense with Taurus, in terms of my actual body!!!
Even the most important raj yoga in my chart is gone with tropical houses. (Very good for timing!)
Ahh!!
