You need to look at the mini 5 arm downstem and just a mini 5 arm diffusor downstem. Not a tree perc on a downstem. What this downstem does is break up the smoke into 5 different mini tubes forcing smoke into the water. True Smoke Diffusion..
The 5 arm mini downstem has no drag helping make the 10 arm tree percolate to its fullest.
These 10 arm trees are not reinforced, if they were reinforced it would have alot of drag, and not work properly.
This piece is like an Advanced upgrade to the Wicked Sands Mini beakers.
Those had a normal 2 or 3 slit diffusor downstem and a Mini 10 arm tree perc.
This piece is a good solid travel piece not to worry on that!!
The Mini 5 arm downstem is a Female 14/20 joint by UST Glass.

I will try to get some action shots soon....
