@natural farmer if you give the paper mod a go I think you will find the answers to your Omni questions.
From what I've seen the OV has a tapered end which I assume mates with a taper inside the Ti tip.
This allows the OV valve to be set where you want it. If you shut the 'valve' completely it will only allow air to pass thru the cap. If you open it fully it will perform like a wood/glass stem with open carb.
I settled on a small hole which allows just enough of a pressure drop to allow me to get good clouds without the 'milkshake' type draw.
@Copacetic this is how my stems look. I settled on a 0.5mm 'carb' in the wooden stem.
Thanks for your time @phattpiggie but I am not sure what you mean with the paper mod comment... How does it explain what I asked? I hope you are right about the condenser but maybe there is still a small gap for fresh air to come in. Maybe someone who has an OV will chime in as well. I have tried creating the effect you described with a silicon ring leaving just a haircrack for air to enter from the hole but again the results were nothing like the ones I get with a closed hole.
If there is enough airflow through the cap to allow for a series of gentle mouthpulls the vapor production is even better than the Lotus and Crafty IME, taste might be better as well...
I also have to say that I think there is something wrong about the standard way of using the Vapcap. From my tests when the hole is open or feathered or pulsed etc the amount of heating cycles (assuming you heat the same area on the cap) that are needed to finish a load is the same with a closed hole and mouthpulls. The amount of vapor produced though is night and day. With an open or semi open hole I don't get nearly as much vapor as with a closed one and airflow through the cap only. Or maybe there is a better way than the intended design? Is it a happy accident maybe???
