My favorite has to be percolator water pipes. The smoke is very smooth while still getting the full effect. Plus they look totally awesome! I just bought a one foot double percolator and could not be happier
I'm hoping it's soon to be my new vap...but for now I like my 6" glass pipe with a flower shaped glass screen. I only pull down the bong 1 or 2 times a month.
...these glass screens are great, if I could quit losing them.
