Hi Mads,
I normally use 130lbs Tufline XP Braid, I find that with the high salinity and heat in this part of the world it works well. Other braids that work well are Verivas and Jerry Brown. Leaders we use 300lbs mono. I use a short leader that I cast outside the rod eyes. Then for lures I would suggest the bigger the better, the smallest I throw is 170gr if the body is tired but try to use 190gr+. But also this is determined by the guys you fishing with, if someone is throwing big lures you are not going to have much chance on a smaller lure (generally speaking) but if everyone is throwing 120gr then you will get hits, all relative.
The biggest problem we are having is that because most of the fish are so big that they are biting down on the lures and swimming with them in their mouths but not getting hooked, no matter how hard we hit the fish, so the bigger the hook the better. I suggest 10\0 Decoys if you can find them. We have broken a few as they are brittle but I think you also get a better hook up rate. Maybe even try the Nomad style and use 10 or 11/0 Jobus??
Hope this helps.
Cheers,
Nick
