Re: PERFORMANCE HOOKAH
I would advise against starting off with a multiple-hose chinese rig like i did, no matter how shiny it is at first. Experience has taught me that they tend to fall apart and/or rust after a few months of use, not to mention the restricted airflow.
It seems that most on this forum would recommend a syrian or KM hookah, and I'd recommend going that direction. My KM smokes wonderfully and I have no complaints so far.
Oh, and as far as the diffuser goes, it's easy enough to make one yourself and save a few bucks. I use bendy straws shoved up my downstem. Same principle at a fraction of the cost, plus they're disposable when they get dirty.
