Zigzags, but as for the smell, you could quickly take a shower, spray cologne or any air freshener on yourself, and brush your teeth or if you're too lazy mouthwash. Try to keep in mind that if you can't make the smell go away try to bring out an alternative smell to yourself that sort of covers up the other smell. But really after smoking the only thing that smells is your piece so most likely no one will notice whether or not you reek as long as you wash your piece if you choose to get a bong. But since you're a beginner a bong can cause many difficulties also inexperience can lead to shitty mistakes. It's best to have a friend give you tips and stuff like that before jumping into huge pieces and such. I personally favor the bubbler, a bit easier to carry around.
