Stemline. I love it so much. I literally find myself wanting to rip it throughout the day just because of how awesome it is. After having it for only 2 weeks I decided to buy a custom worked ash catcher from them to match my worked stemline hybrid. You cannot go wrong with SSFG.
Also the size of the actual tube part concerns me, looks a bit small an difficult to fit your mouth in
I got rid of it because I wanted something other than a stemline. It is a small piece small mouthpiece. I would recommend it though. It stacked pretty high. Beaker is just a beaker. You will get bored quickly.
Does it pack a nice punch though? My two pervious bongs have been syns with some perce and they were boring and too big.
