I cleaned out my tackle box today. Had a chuckle at the 2/0 hooks I bought years ago for catfishing. Well, I obviously need to upsize. Can someone let me know the difference in Circle, Octopus, & Octopus Circle hooks. Do you let the fish set itself like circles. Why do some have offsets some don't? Also does anyone know where to order OWNER hooks online? Thanks for any replies!!
