Follow the instructions on smoking dude. If you want to conserve (which we were not) you would want to load small bowls. Like half point - point bowls. (50mg-100mg) Heat slow, roll it normally and far, with a nice slow steady inhale. Hit should take anywhere from 20-30 seconds or so, depending on how much was loaded.
We on the other hand were more focused on getting hew-fucking-mongus hits almost every single time we hit the thing. That was loading the .25g bowls, and just toasting it. Heat fast, roll it fast and barely back and forth, and pull hard and steady. Hits took about 3-5 seconds.
Though, we did go easy on that one bowl. Shared between five people, it went around a good five or six times.
