I have had this Tag Super Slit Bellow UFO for a bit. At first I regretted it. I thought it was too big and it had pretty serious blowback. But now I really dig it. It is fun to fill, and nice to hit. No the most flavorful glass that I own, but doesn't steal too much. I tamed the blowback with good coordination on a pass-through carb and a low water level. I think putting in just enough water to cover the slits is what did it. Now I can sleep on the carb a little and still avoid a duff storm.
It says it is a second, but I can't find any flaw. I do like the perc on it a lot and I think I would buy another piece with it. Looks like with the current BREAK-35 code, you can still get it for $60.
