I personally have no issue with sending guys to train with the Boks. Me personally would send a lot more guys to the Bok-camp. It's a way to show them where they could be one day if they keep on performing. Some sort of incentive for the youngsters. And if it will aid in shutting up the ANC and whoever else, then send more Black guys there, why not?
As for Senatla, his pace is something to admire, and his switch between XV and 7's looks so easy. He is definitely someone I see in a bok jersey one day. he just needs to limit his injuries, and work a bit on his defence.
