Normand:
The rule that I use is the length of the body, it should be just a little more over 50% of the shank of the hook, on the kink shank hooks that is usually just past the kink. I prefer the kink shanks because it helps keep the head from turning. I have used stinger hooks by tying a piece of 50# mono on the top of the hook and then putting super glue on it hold the mono in place.
