I've gotten better adjusting various things, but I've yet to get a consistently roasted hit after playing with ALL of the variables. The top is dark, and the bottom is just a light roast, and then there's combustion. There's no middle ground and I've adjusted the air flow, the stem control, lighters, different packs and material, Wand temps. I get good hits (usually) if it's not quitting on me before I'm done.
Granted, this is with the boro balls, I thought I liked the punchier hit, but I'm about to switch back to the original zirc balls. I like the vape, but I'd really like to continue to try to dial it in, but I'm tired of wasting bowls on combustion too.
I can't even get it to light roast really- it's the dark roast top with light bottom or combustion. I try not to mention other vapes in this thread, but my only other butane experience is with the Anvil so I'm thinking part of the remaining thing to figure out is the heating (torch or Wand, the Wand lends to inconsistent roasts too!) and maybe my draw.
Again, I like the vape but no matter what I adjust, I'm getting the same experience that I find hard to dial in, which seems odd with some many fiddley options.
