I've become a big fan of pinching down all the barbs when I go on a trip. Just don't need to take that chance and also I figure it makes it more of a challenge to land a real fighter. The concentration has to be sharp to boat those high flying smallies. Personally I think all hooks should be barbless in both parks. I think a lot of fish are killed each year by spending too much force and time getting barbed hooks out.

It's also that second/third set of treble hooks that do a lot of damage. Removing all but the back set is another safety step for both you and the fish.
