Questions on switching realms?

I'm looking to change realms, since my realm's Alliance pop is dismally low, and I'm usually the only Ally player in sight. Needless to say, it's hard to find other people to do content with (as in just running around in the world), and even though I'm in a very large guild, there are only about 10 people on at a time - it's hard to get a consistent group on for raiding.

I've looked at a few realms and have some prospects in mind. Just have a few questions before pulling the trigger. I enjoy seeing Horde and engaging in occasional world pvp, so being slightly outnumbered is not an issue, I just dislike being the only ally around, or being outnumbered 10:1. The realms I'm looking at have a lot of 110 Ally players, way more than my realm, but about twice that in Horde.

On paper, this does not bother me, because I assume that there is enough (A) activity and people out in the world that it doesn't matter there being more H. That's what's making me lean towards these realms which have more H. I'm afraid that if I go to the realm that has 3:1 A:H will have me seeing very few H around. Not that it matters too much, but it's more fun to me if t here are a lot of people from both sides around.

I've read posts about this before and people usually answer that CRZs make it a non-issue, but even so, in Broken Shore areas there are always 10:1 H and I'm usually the only A in sight, regardless of CRZ. Even in old areas, I don't see many A. So I guess my question is: would being in another realm with more H than A (but way more A than now) fix my issue, especially with CRZ, or should I just opt for the realm with more A than H?

Thanks in advance.
