No need to flame, you make the decision that is best for you based on your experiences, and I will make mine, they don't have to be the same. I have my reasons based upon personal experience. Bull shark came after my buddy Danny Long....we knew he was there for awhile.....Danny was your style, hang onto the fish, and get to the boat. That shark came in on Danny and latched onto the bag, which me and another buddy had to cut free from Danny. Once the bull had the bag, we surfaced in a calm and orderly fashion....bull didn't come after us. I am not a violent person, and I don't condone striking any animal, but if that Bull came back up the line at us, I would probably have struck him with the Speargun or stabbed him. This shark was extremely aggressive. I have seen sharks on many dives (see my photos), but never one like this, and when the bag was gone, the threat was gone.....at least long enough for us to get to the surface. Because of this incident, my speargun now has dry-rotting bands, and is basically there for folks I know to borrow. I have since traded in my gun for a camera. Although, I may stab a flounder or grab a lobster.....my spearfishing days are OVER.
