So when you're using a vape on demand, like the splinter, you hold down the power button and start inhaling, then when you let go of the power button you keep inhaling to clear the hit so there's no residual vapor left in the glass stem or rising from the bowl... So then when in cruise mode, you're not using the power button to clear the bowl, you have to remove the heater entirely to do so, just like if you were using it on a bong with the WPA... This is why I don't think I could ever use a carbed WPA though I do like the idea in theory, my ocd would be too worried about vapor rising condensing on the heater.
You may find it difficult to do cruise with the nub, also it is some difficult to use upside down like I was saying, but that j hook will be perfect! I have the same mini J-Hook, but with a female connection, from when Lamart was telling them that way. Next time I make an order I hopefully will be getting one of these new male connection ones too!
I have a wooden capsule stem, short and bent inserts with the amaze cooler which I love, but I'm actually not really a fan of the s& b capsules themselves, so I wish it wasn't cut to fit one and that I could use it with the rimmed basket screen instead lol
