We did it once.
If you want to do a Shark Dive, sure, it's worth the time.
Pay attention to the dive briefing, it can have some minor current that will present new situations to many. Hang onto the down line. I don't think they've lost all that many people in the current.
Take an additional 6# of weights above your norm. Helps to make you go kerplunk on the sandy bottom and not bobble around.
Shark Dives can be of interest, but will not compare to a chance encounter in the blue. If you continue to dive enough, you'll have that totally different experience.
