Jerkbait Split Ring Size And Hook Brands

Fellas,

I'm looking to replace the stock hooks and split rings that have come on the Smithwick Suspending Rattlin Rogues. I know the hooks come in a size 6 so no worries there. In terms of split rings, does anyone know what size Smithwick uses? From what I've tried to dig up, it seems most of the bass lures on the market use size 2 split rings. Also, any specific brand/style of split ring and hooks that I should keep an eye out for?

Thanks in advance.
