At the suggestion of John Nappo (JohnTFT), I started using Charlie Brown hooks about three or four years ago. As was mentioned above, the welded rings are smaller diameter than used by other manufacturers (and I too wish they were slightly larger in diameter).
That said, I fished a puffer fish on a factory ringed 5/0 Charlie Brown to land a 307# on a trip last spring. By correctly tying a knot that goes through eye of the hook twice (I used a Trilene knot), you distribute the the forces across a larger area mitigating the effects of the smaller diameter factory welded ring.
p.s. I believe that the hooks are available without rings if you choose to ring them yourself. Photo shows 5/0 Charlie Brown and an 8/0 Eagle Claw 2004/2005 for size comparison.
I've used all the ringed circle hooks and had success with all of them, but since I started using Charlie Brown circles, I'm pretty sure my rate of getting bit has gone up. They're also just a little lighter which probably helps a bait to swim easier. On the other hand, it might just be a biased perception based on a small data set-----even so, I've got a 220 on a 5/0 so probably they're pretty strong, and have a 281 on a 12/0 in a big bait. Even if they aren't better, I'm sold on them just because of my confidence in them, and that's probably most important anyway.
