Anything worth doing, is worth overdoing.
Oh I am using it with bottomless banger exclusively now, and bubble cap, all clear so I can see what's going on completely!
That is a sweet setup.
I'm sure the cooling effect isn't as good, but I like the look of the new glass housing they offer for the DT V4. You get the better view over metal. I wish they made one for the Sai. The motar glass top works in a pinch.
