IMO, revealing that we suspect also that the starts are quite similar if not mirrored would be the way to go (and to state that the land south of our locations as far as we know do not seem that much mirrored). The info is not that valuable really since RB is going to know it soon enough anyway. I can't really see what they could do with the info to change the game. What we gain is continuation of open and honest discussions. BTW, I like Grant's idea of asking about mountains as well. Keeps the discussion going.
