Referring to surf fishing, ./// Are you sure chunked bait is the way to go?
For the most part, you lose some things while bait fishing.....2 things that go hand in hand, Distance + you'll definately be covering less water, not that you always need distance, but depending on where you're fishing, it could mean the difference between catching something or nothing at all, nevermind a 50. Not to mention, crabs won't normally pull your plug under a rock

, skates and dogfish prefer bait over plastics 2 to 1 according to the last census,..// etc// ...you can fan while baitfishing, but it won't last as long with the continuous casting, the eel being the exception - but you'll still lose distance with eels. How many casts can you make and how much water can you cover with a plug versus 1 cast and turtle retrieving an eel???
Think about it.
I still think BAIT, alive or fresh would be my answer.
