without letting us know where your heading to we cant give any advice but in case you check back and im not on ill just give you an idea of what im going to use tonight.
I head out of Dana point and Lajolla on a reg. The gear i biring usually consist of three rods, one calstar with a coventional reel calcutta 400 with 15lb test. Second rod i have handy is a Gloomis Bacura 8ft rod a tinidad TN40 with 20lb test. Last rod i have is a 7ft rod Gloomis IMX rod in case the bit is slow and i need to fish for some bass. The other two rods are for Yellow tail tuna, blue fin tuna and albacore. If your going on a 1/2 day most likely you will be heading to Horseshoe kelp or hungtington flats there you will most likely be fishing for bass,barracuda and maybe a few other odd fish in between. For that type of fish you can use light gear such as a 6ft rod with a spinning outfit or what we call them, coffe grinders. If you never touched a fishing pole before, well then a spinning outfit is for you. Make sure it is outfited with 8lb test , wait no maybe 15 for you since you sound like you dont know what you are doing. Now if your going on a 3/4 day or full day trip then most likely you will be heading to catalina or maybe even San clamente island and you will need the gear i listed above.
Anyways its nice to get out into the water and i hope you guys go to the Flats, there you are most likely to land a lot of sand bass.
As for me i gotta get some ZZZZ. I gotta hit up a few spots tommrow and catch me a Yellow fin!
