Circle hooks work great, I suggest experimenting with different brands and sizes. There are many different shapes on the market. I tried a few brands that I had less than a 50% hook up rate with on the sharks. This is why i began modifying sickle hooks into circle hooks, bringing my hook up rate to over 90%. I will say that they are unbelievable in preventing gut hooking, since making the switch to circle hooks, I have landed 100's of shark and not one swallowed the bait, thus ensuring a way better post release mortality rate. The trick is absolutely to reel in any slack, and raise the rod slowly, as you reel into the fish, instead of the big aggressive hook set.
