We have been using braid for several years now, mainly Finns PRT or Berkley Whiplash. Because of its fine diameter, 20lb is about as light as you would want to go, and 30lb is easier to fish with. That's about equal to 6lb mono in diameter.

If we want to be 'sporting', we can always release them after the photo!

Fine braid allows the use of light-weight reels like the Shimano Curado and still handle fish over a metre, especially from a boat. A decent rod is mandatory, my everyday baitcaster is a GL-3.

Before braid, we used 6kg mono pretty-much exclusively.
