I only use a phunnel and Mod, so i put the tobacco in around the Mod, and i fluff it up with my tongs or fingers, but i'm getting really good with my tongs so usually only tongs.
. i make sure the tobacco isn't above the rim, and then place the foil on top. I then proceed to poke holes, usually three rows, the most holes on the outside, the middle has the least, and the inner-most has an inbetween amount, enoughh to allow airflow form all angles to the mod. I then shake the bowl around to loosen up the shisha and blow into the bottom to create good airflow.
