For your first setup, I would use 30Lbs braid so you can have the power to reel it in fast and also since braid has no flex you can flip and pitch it better than fluorocarbon or monofilament. For your second setup, I honestly don't use flukes so I can't give you any advice there. For your third setup I would also use 30Lbs braid so you can have the right action with no flex.
