To add to this convo-- I'm running a stretched coil that formerly lived in a B1. Came from CH originally and I didn't modify it when changing setups, just unscrewed one and screwed on the other. All 3mm rubies in the 2.0 vs mixtures of 3/4 in my B1 and my B2.
I'm running it at 600 even and it's never come
too close to combusting but it is very capable of the dark roast at that temperature.
The craziest thing about this setup though is it never seems to stop finding more vapor in my bowl even when I think there's none. And to top that, if I don't heat soak the bowl before I start, I can legit just rip this thing as hard as my lungs will allow and it stays light brown while producing endless vapor. It's like I found some glitch in the matrix. Makes no sense but it also makes me higher than a fucking kite so probably most of my observations at that point feel like they make no sense.
Final thing I will say is I was pretty convinced that my tolerance was over the moon and there was just no way I would get stoned again without a serious T-break in my future. This thing smashed right through that
it's honestly kinda freaking me out
