As a general rule you can use a hook one size larger or smaller than the hook size for which the mold was designed. That said, you could likely use a 5/0 style 91768 in the 5/16 oz. cavity but anything more than that would likely require some mold modification.
Even though this mold isn't a "jig" I suppose, it is in the "jig molds"section of the catalog and the web site so I'm going to move this down there to Bass Jigs.
