I have been using 6/0 Gamatatsu Octopus Circles for a quite a while and LOVE them. Besides the great hookup ratio, there are other benefits. When I do miss a fish, the eel is still there, on the hook, and ready for a 2nd chance hit. More importantly, I generally fish rocky areas and the circle comes thru the rocks/weeks with far fewer hangups than a conventional hook. There was a bit of a learning curve, but I may have forgotten how to hook a fish with a J-hook

. Good luck.
