That answer eliminates 8 as a core. 9w8 isn't out of the question, and I actually had 3(w2) in mind, but if you're often secure, then it might be integration. Find what you can from audio of teachings and books and excerpts in the pages to really be sure. A person who knows you better (some from here use Skype and I may use my account again when I have my own PC again) than just seeing some posts is probably going to be able to give you a lot better insight.
I'm thinking it's on that 3-6-9 triangle for the core but am not definitive on it. I actually am a lot more focused and even faster with work when I'm riled up and my core is 6w7.
