This sounds fine, although you can also draw faster, with the three, the airflow is designed so you can chest inhale normally and it will regulate for you, so all you have to do is pay attention to your button feathering? If you get some scorch, that means you need to lay off the button a little quicker and keep drawing with the residual heat... I definitely used to use a plain short stem with my earlier models, even the short basic cooling mouthpiece is a similar experience with just a little bit of cooling... Eventually you can get better at using in hooks or other although water I never felt to be ideal, I have a lot of other cooling connections with WPA though not everyone has a proper 19/19 WPA you can get them from GVB at least now...
Alright so based on what you listed, the brick is the closest analog, to the unregulated pure convection on demand experience, although of course very different! If you can, try to only use Milaana for a while, the more you hone in on the ritual and variables for yourself, you can get the most out of it... In my experience this is always harder to do if you are rotating other very different vapes (basically needed to focus on using only that vape, when learning a very manual pure convection on demand and especially unregulated vape, for learning well myself)
