Re: Distance between colas foil and tabaco.
honestly the reason no one can some to one answer is because everyone likes and expects differant things from hookah. some of my friends take a tiny hit and say its harsh while i will puff away and be fine. some people here put on 1.5-2 times the coals as i do with the exact same bowl and shisha but i get burnt to all hell if i put that much on.
in general you will have less issues if you leave a gap, but with quick lights there is a gap under them so they dont touch the foil (i think that helps but im not to sure).
personally ive just gone to the phunnel cause it requires less fluffing and making sure you can pull well through it and all. and just pack it to or just over the center hole
