Mate just depends on when you are going to fish, during the day I fish with 4000 series reels ABU Soron STX with 6kg mono and 30 lb leader with 12 ft rods 8-12kg allows you to cast further when the gutters are out a bit and allows you to put a bit of grunt in for the bigger fish like salmon. Don't like light braid off the surf, keeps knotting up with the wash. Also the light gear allows me to move around a bit to find the fish.
At night I fish the same rods with 6000 reels with 30lb braid or mono as well as a heavier old favourite snider 13ft glass rod with a 7000 ABU and 15 kg mono, overheads are a nightmare to cast at night with braid. I use IGFA rated monos as they are thinner with less memory, casts well. Good luck with the choices
