Try a range of plugs and soft plastic but definatly take some of these http://www.harrissportsmail.com/Models. ... elID=15056
in 4" and 5".
If you're taking plugs etc, change the splitrings and hooks for 4x strong saltwater jobbies. These fish have destroyed size 2/0 3x trebles on my lures so many times you wouldn't believe it.
I personally like at use a 20lb Berkley Fireline mainline with a 60lb mono leader of about 18" tied on with a double uni knot. Locals use wire but we get better results with a mono leader although you will need to check it for fraying every now and then.
The uni knot beats a swivel conection every time because you're fishing at night and will eventually knock the liner out of you tip ring with a swivel. Practice the knot until you get a good strong connection - we use 4 or 5 turns on the mono and 7 or 8 on the fireline.
For clipping on lures, there are lots of options but my number one choice would be a Breakaway Fastlink. These things are incredabley tough and have never let me down.
