As a borderline gram weenie the thought of bringing anything made of cast iron in my backpack gives me heart palpitations.I hear carbon steel is good too, though I'm unfamiliar with them. I'm an old Boy Scout, so cast iron makes sense in that regard. Can you use carbon steel on a campfire/grill? That's one of my favorite things about cast iron - I can use the same pan and/or recipes regardless of if I'm camping or at home. I've had some friends give me a hard time about setting up my "kitchen" while camping, but then they see their dinner vs. mine and their attitudes change!
