I've seen people have trouble with Momoi line, Jinkai is superior. I remember when all the rental rods had circle hooks, that lasted a few seasons and went away, nothing like GUT hooking a big yellowfin, you can bleed it while reeling it in. A lip hooked tuna will fight forever, a bleeding gut hooked tuna will give up faster, why I like those big fat Owner Gorilla hooks.
Either of those spinning outfits will work fine for mahi. When you speak of bait fishing it could be live 2 lb chub mackerel or squid, so a freshwater rod can be brought along also, just TRY not to over pack.
