For a good hole amount you want the same amount of restriction in airflow as your bowl provides, that is take a draw through your bowl without foil (naked :O), then place foil on and punch some holes with something atleast mostly sharp; toothpick or thumbtack dealy. Then take a draw from the bowl after you punch some evenly distributed holes, and just keep going until is was like the initial draw, without going much past that.
Know what I'm saying?
