The thing is if it's packed loosely (which I think is good for better/more even airflow), doesn't the herb fall against the top of the cap if turned upside down. I would think that would have a negative affect...
What @BabyFacedFinster said...I don't get herb in the cap, even with small packs and inverting into an IH. For the most part, once you get the first heat cycle going I believe the melting resin on the flower holds the herb pack together.
On the air port discussion, when using a VC at home and with glass (water) I tend to use an airportless stem or a stem that has it's airport blocked and my JarHead IH. When out and about I use a torch, and I like to feather the airport much of the time so I usually have my Omni along to give me options.
