Id like to go again, with the stuff I just picked up.
1 - around 8 or 9, lasts a good 2 hours.
2 - Either my bong or glass pipe.
3 - Definately a 3, some of the best I've ever had, no name though. It's absoluetly covered in white hairs and I can smell it when I walk into my room.
4 - Everyday, multiple times.
