does anyone else have a stem like this? http://i48.tinypic.com/o0aumw.jpg i got it for $20 at my lhs and I am not sure if I like it at all. I feel like it gets clogged, and adds decent drag - But i am not sure. I am new to bongs and this is my first bong. It is a single 10-arm tree perc left coast, beaker base. I have some no-name ash catcher that is decent too. my lungs aren't beastly and I cough up a lung every time I hit my bong anyway, but thats ok cause it gets me super baked... but there is always a lot of smoke in the ash catcher and im having trouble getting it to get into the rest of the bong easily. I feel like it might be this downstem. Should I just get a diffused downstem instead? does anyone have experience with downstems like these? I don't really know if it was a good idea to get it.
