@Summer Rr: Nayshstyle without a condenser.
I'm starting to dial it in and the results are pretty remarkable.
I'm basically doing what is now an 'intuitive' mouth pull with a breath of air followed by 5-8 second lung pulls with the carb covered. I can usually do two per heating cycle.
The mouth pull is to generate a bit more heat, and negative pressure I believe, then a pause for a breath (so I don't die) and then a longer harder lung pull. It's a bit more like using my Milaana as to how I'm responding with draw strength and type. And I don't use the carb open ever. The carb introduces to much air into the proceedings. It's easy to see why most custom stem makers are staying away from those.
I do hope that someday DV decides to investigate carb-less stems in both metal and wood.
