HELL, BRING EVERYTHING!!
Unless you have a specific species you are planning on targeting you really need to be prepared for anything. The end of March really isn't considered prime Yellowtail time there but this weeks report on mexfish.com has them catching them up to 30# when the weather allows it. Bring everything with you and then take out whatever the conditions and your plan for the day dictates.
10# bass rods are a kick for cabrilla and triggers. Don't throw back all of your triggers. They are great eating. The trick to cleaning them is to poke the knife into them then cut from the inside out. You need to bring a stone regardless.
20# and sabikis will get you bait and work well for larger cabrilla or tossing iron at Yellowtail boils.
40-60# for yo-yo and with 60-80# you might be able to turn that Grouper before he rocks you.
Of course the winds are always a strong possibility at that time so you might not have to bring anything.
If you check out the archives on
