If you want to fish for the "Big Boys" then try going to www.ulua-fishing.com.
They talk about all kinds of fishing in Hawaii but primarily for Uluas (Giant Trevally). The gear you stated would be sufficient for "small game" like Mois,Oios,Papios,etc... but will be too small for Uluas. The gear we use are 13'-14' rods and conventional reels that hold at least 300 yards of 50-100# test.Lead weights between 8-12 oz.--- If you go to the above website,look at the "Casting" thread and go to the Jerry Valentine visit. There's pictures of guys casting this type of rods.---Try using circle hooks locally sold as "BKN hooks" in the size ranges about 22-26 with your setup that you're bringing. When you get here try calling the local tackle stores to buy fresh bait called "Tako" or Octopus. The supermarkets should have Calamari and maybe Aku belly. These would be good baits to dunk with.----If you bring your Salmon/Steelhead rods in the 9-10' range,these would be good to whip with.A reel with like 8-10 lb. test and 1/2-1 oz. leads,leaders from 6-12 lb. test and locally available hooks called "AH or MZ" hooks.I think they sell these on the mainland as wide gap hooks.Odoul hooks work good as well both in the 10 size and a 2" curly tail grub will work.---Will try to post more later but try checking the thread on this board about Uluas in Hawaii in the mean time.
