Re: No foil ?
There is a video review of Naklah Zeghoule (spelling??) posted by madwolfe, gothkid, and anhonestpuck. They smoked the zegholue with the coals ontop of the shisha. They also have a how to pack the tobacco video showing you how to pack it right without using foil.
Personally myself, i dont think i am a fan of the traditional flavors, or plain. To each their own.
