Rob,
Yes, about that close to either the 3.7 or 2.7. I tend to listen to one pair for a couple weeks, then swap them for the other pair.
Angling varies depending on how wide I've placed them or if I desire more lively sound. I only ever use the tiniest angling in when I do, but usually no angle - facing straight ahead. I still get excellent center-fill, even from the wide spacing and not angled in.
