I have watched GT chase food on Molokai, at least 30 maybe 60#, very active. Ulua, big Papio, are not easy or abundant. I am sure I would have tried the fish with my 8 weight if I was close enough but probably best to save my gear for the bonefish (oio). Watching my expensive fly line disappear over the edge of the reef with no replacements available is not a good idea. On Maui, respectfully go talk to the locals fishing long rods off of the lava edges, you will get the idea. Check out Clay Ching's recent catches on his web site, decent GT (Ulua) last week.
