I read that moon vs moon in synastry is very good. I can't remember where I read this; it was years ago. However, the astrologer was reputable, and may have even been, Stephen Arroyo.

I have never seen this in practice. But whoever the source was,  they were so credible, I'm still thinking about this, thirty years after the fact.

Have you heard this or seen it? If you've heard it, what was the rationale. If you've seen it, how did it play?

Thanks.
