For a 'brand', I like Susan Bates brand because the hook is more defined, than the Boye hooks I have. The 'hook' is deeper to really hook onto and hold the yarn really well. I recently picked up a size Q hook (which is HUGE, LOL) to try an afghan or two with a gigantic hook. Most of the projects I have done (4 afghans & 3 womens tops) have used hooks G-H-I.
