The nameservers listed in the parent domain are by definition the
authorative ones. Which one gets a query to be answered authoratively is
essentially random. So if you need more steam you add more authorative
servers and list them in the parent. After that if you still need more
resouces you can start using anycast. See how the root servers work.
They certainly don't use load balancing.
