Amazing! I would love to do that. Great whites are beautiful animals.
I think that cage diving does more good than harm. I heard that it has altered the behaviour of sharks and theres no way of knowing if that could be a detrimental thing. But we can know for sure it brings awareness and reverence for these ancient, perfect creatures. They never need to change, sharks, they are great just how they are. that's why they are called "great whites"
