Circle hooks work great for halibut because once they&';re set in the halibut&';s mouth they simply don&';t come out. A second advantage to a circle hook rig on a mono leader, is that the fish are much easier to release. The hook nearly always ends up in the corner of the halibut&';s mouth and not inside the mouth or even worse, down the halibuts throat. So you can get a solid hook set easily. Especially if you do not set the hook. Let the Halibut munch on your bait a bit, and slowly pull in your line. Your hook will embed itself in your catch right in the corner, and he&';ll be non the wiser as he is swimming away, but already caught. 14/0 or 16/0 Circle hooks 200 lbs Mono
