I've never really used glass, not as a smoker, nor since exclusively vaping herbs for 5+ years. Only glass parts I have are Solo stems and a bb9 attached to the miniVAP. There is a water rig stashed away somewhere, and I am actually intrigued to bust it out again soon.
To me, it is all about cooling the vapor adequately enough. I remember taking my first draw off the brand new MV with the standard silicone (flexicone) tube and having a huge coughing fit. Took too big a rip because I was new to this kind of power in a heater and the tube did next to no cooling for me. Tried that little small mouthpiece and really felt the heat on my tongue and throat as well.
Haven't really coughed since attaching different stems and mouthpieces.
The mighty also seems pretty easy to handle. But taste wise not quite up there in my opinion.
As others have mentioned, the Bowle really does a fantastic job with cooling without further tinkering. It has its limitations (temps!), but level 2-3 are delicious, intense, and so smooth. Even on level 4 I never feel too big of an itch.
Will be testing a TM2 hopefully tomorrow and already looking for wooden stems ( perhaps with glass inside ) to adjust for more cooling, if needed.
Above all, keep yourself hydrated. Vaping and a nice beverage go hand in hand. Or as with the Bowle, go in one hand. I never use the attachment though, too cumbersome for me.
