Like you, I identify with all the limbic qualities you mentioned. Most people would probably see me as a calm type. It's only the people I know really well in real life and sometimes on forums like this where I allow my more emotionally intense side to show.
I think though if you're at either extreme, that could be problematic. A balance is good. Imagine being so calm that there is a real problem or crisis and there is no emotional reaction whatsoever or you are unfazed by it and do nothing to resolve it.
