a good rod for both is the gator t90L or t80L. they're stiff enough to throw a ling jig or heavy bait without hitting the back of your head. and still have enough action to throw king baits (where most cobia specific rods are a bit too stiff and many baits are thrown off).
i have a t90L with the butt section glued up. if youre interested, ive got a few different guide setchoices. and you can pick the colors. send me a pm if youre interested. or call me at 206.6560
