I would go to 5/0 or 6/0 hook and hook behind the dorsel fin. I would let them load the rod up hard and let the hook do it's job and you got them. Best advice I can give you for circle hooks.

SangamonCatKiller said:Bank Catter, I have to ask... what type of situation are you running those circles in? Based on the fact that you are missing alot of hookups it could be the wrong one. I use 7/0 to 8/0 j hooks for all my catfishing. I cannot stand circle hooks. Keep in mind this is strictly my opinion but, I hate them. You cannot set the hook whatsoever with a circle hook. Instead letting the fish hook itself after it runs 20 yards downstream. I would much rather set the hook and feel the power of p'o'd flathead then let him hook himself. Imo you should switch hookstyle altogether.
