Mt Adams (kings ravine)

I'm taking a trip to New Hampshire next week to hike Mt. Adams. I've read in a few places the ravine is 3rd-4th class. Any one done this? Is it exposed enough to warrent roping up with a non climber? If not, is it worth bringing a rope and small rack? I hear there's some decent bouldering but also worth the rope/ rack. Thanks all.
