@Drug, the Marley looks great and we're so glad that you're honing in on your technique! It sounds like for your style, approaching the bowl at a lower power setting may be a good idea. Also, taking a few "sips before you rip" can also minimize charring. Taking those first sips "primes" or "stokes" the bowl--increasing the temp of the whole herb, not just the top. This can even out the extraction.
We also advocate for some pretty serious tamping of the bowl. This can be hard to do in shallow bowls, but it can help create a more even extraction with fewer hot spots. All y'all who advocate for a loose pack... well, feel free to try it out and weigh in. I used to think that way, but a
little LOT of experimentation convinced me otherwise--at least for convection.
@Trackrat, looks like a sweet setup! How's the AVB for you? Seems like you might get some pretty even toastings with it.
One of things we've discovered is that "every bowl is sacred" (cue Monty Python music). Each bowl is unique. Each pipe will have different airflow. Each varietal will extract a bit differently (due to moisture, density, terpene profile, etc). And, each person enjoys their vapor differently. Vive la différence!
