Less is way, way more.
Here are my findings, so far:
I'm using, for a single dab in the VXN, just about a crumb of shatter/crumble (either one - a bit less shatter than crumble, per se). About a fourth, maybe, of what I would use for a dab on the oil rig (which is about half a "normal" dab size, from what I see in person and on YouTube)...
we tried to weigh one, a couple of different ways, and the closest we could get was about 0.03 g (excellent scale from amazon).
The EVO is set to Noon. I have not detected any advantage, yet, in going lower, and going higher seems less desirable to me at this time.
Try not to drop the VXN into the bamboo. I am catching myself.
It starts vaporizing so quickly, that I don't really need to pre-clear the tube.
I can almost finish the vapor cloud... the rest burns off nicely; just about when the bamboo goes green again, at full max, the residue is gone.
I've got a video, that pretty much sucks. I'll be back soon to post it. Really.
Oh, hey... and the effects I'm getting from this tiny crumb of concentrate, at a lower temp, is really, really deep.
