If I were to only have one, my dock set up would be a medium to medium/heavy 7-8' rod with an appropriate spinning reel. Outfit yourself with some two-hook bottom rigs and 1/4-1 oz weights. Use just enough weight to hold bottom depending on how the tide is running. Cut bait, live minnows and especially blood worms will work great. My go to the last couple of years has been these sheets of imitation blood worms. Tough as nails and if spot or croaker are around they will nail them. Then use croaker or spot for fresh cut bait to catch something bigger. Berkeley Gulp Saltwater baits work great as well.
