I believe there was a thread about hooks that is most likely hanging off somewhere deep within the general forum.
For myself I've used some fairly small hooks like size 1-2 Gam's to pull in some large springs, but a couple years ago I went to the barbless hooks and literally had fish throwing hooks out less than a minute after hook-up. There is a noticeable difference in the quality of the regular shaped/ barbed Gam's in size 1-2 to the barbless ones, thinner wire, easier to flex apart, and the shape is more rounded which is making me suspect I've had more fish roll the hooks out of their mouths especially with the more flexable wire.
Last season I switched to Maruto sickle hooks cause they felt way stronger and the price is pretty much the same as Gam's. Hook size is similar to that of a size 2 Gam but Maruto calls it a size 8, after hooking into multiple springs I was actually impressed with the strength these hooks have for their size cause it looks more like something you could use for smaller fish like stocked rainbows.
I've personally liked to use smaller hooks when river fishing and hooks like 2/0-3/0 for ocean cause of the heavier line used when trolling.
