I have a MNH glass phunnel and a glass screen. I don't use foil.
The phunnel was tightly packed with the screen slightly touching the shisha as all the vids I saw or tutorials I read indicated. Scoop also said that's what he did the other day.
AF is much easier to pack too, from what I hear.
I haven't tried tangiers with jap easylite yet, and I also have a box of exoticas coming to see if I like them better.
Anothing problem is I cant use a wind cover with the glass phunnel as its too tall, so I built one with foil but it ain't as pretty
