Piers can be tough on rods. We like Ugly Stiks. We use 12' beach rods for casting distance, and 6' stout bigwater boat rods for horsing big fish. You'll want at least one of each on most piers, because depending on conditions, you may want to do both.
“Which of you, if your son asks for bread, will give him a stone? Or if he asks for a fish, will give him a snake?" - The Messiah
