FAVORITE FISHING LINE?

what is yall's favorite fishing line. for bass fishing i like stren in 17# test. it works well for specs to but i was thinking of using some kind of braid due to a higher test # and smaller diameter. mainly curious about salt water fishing. also i lost all of my deep sea poles due to katrina and i am about to buy some new ones so input on that type of line would be appriciated as well! ya know for sharks, jacks and bigger fish of that sort.

thanks in advance for your input
