MUZZY. penetrates fish and water very well. The point stays tight when shooting and landing fish. They stand up very well to rocks. You can buy different replacement points for them. One for soft body fish and one for fish with tough skin. The only thing I don't like about them is they change the threads on the tips every so often so the replacement tips you have on hand does not fit all of the heads.
Before the Muzzy, I used the Stingeree. I have also tried the Warhead, but it comes unscrewed when you shoot it. Have also used Aquakillers, pure junk, along with some other junk heads I cannot remember the name of.
