My husky is the most laid back mellow fellow you'll ever meet. And he's still a puppy. I was really worried about him, knowing what the general consensus is about the breed and their energy levels/exercise needs. Turns out, lots of huskies just have really laid back personalities and they don't care what people say.
Disclaimer: He's 3/4 Husky and 1/4 black lab. AND everything I read about this mix and everything the vet recommended to me regarding feeding and such turned out to be completely WRONG. I have an unusual dog. Not complaining. He's the sweetest. I guess I'm just trying to say that even with what you think you are going to get in a dog, they'll be how they are regardless of what a bunch of books and articles claim. So you really never now.
I know that doesn't answer the OP's query. Sorry. I looked into Klee Kais when I was researching a bunch of different breeds, but they didn't fit the bill for what I was looking for and I moved on.
