Capt,
I like 150 pound mono for most of my offshore rigs. As far as colors, for cedar plugs you can't go wrong with natural(its amazing that trolling a stick with lead on it will catch a tuna

)
For squids, natural, pink, blue and white, and green I would say are the most popular. Size, I like any where from the small ones around 5 inches up to the big 'uns around 10 inches. I've become partial to the 5 inch ones used in mini spreader bars and I'm sure they would work just as well in a daisy chain. I would make up some in small and a couple in big...you never know what the fish is feeding on so its best to be ready for anything.
Never used the artificial ballyhoos except for using them on a dredge, so can't help with how they work rigged like real ballyhoos.
Lures for dolphin and tuna...chugger style or jet/cone heads. I've also had success with Rapala's on tuna. Colors...pinks and greens and yellows for dolphin and blues and purples and greens for tuna.
If you need help let me know...be glad to offer assistance.
Catch 'em Up!
