Personally I prefer to use circle hooks over j-hooks for broadbill swordfish.
Every one has their personal preference but I have had a very successful hook up rate on our SwordPro Circle Hook Rigs. With circle hooks I believe you get less fowl hook ups that have more potential to pull out. The circle hook rolls into the perfect position in the corner of the fishes mouth which is the strongest hook up point.
I only use circle hooks myself as these are what I have had the best success on and you have a much better chance of being able to release the fish using circle hooks.
