If you're live lining bunker or macs, or fishing bunker chunks, I'd go with 8/0 minimum. I use the "baiting ease" test. I've tried using 4/0 - 6/0 for live lining 10" macs and it's almost impossible to get them dorsally hooked. 6/0 is OK for eels and clam bellies and I'm guessing 4/0 would do for worms, but you might want to go smaller, especially if you're considering grass shrimp.Trying to decide what size circle hook to buy for bass season. Any thoughts?
