Volute of Vapor
The first times I used my Pax3 I opted for the raised mp but I found the vapor stream to be very hot on my lips, so I tried the flat mp which was surprisingly a lot better about that aspect and even smoother vapor.The flat mouthpiece seems weird to me, maybe because it seems so alien to me. My lips just want something to grab onto, so I opt for the raised piece.
On the debate about half pack lid versus full pack lid I want to say I'm using the half pack lid the most BUT , when I have a long car drive (+1 hour is long for me!), I grab the full pack lid, with a tight pack of well grounded flowers and I'm ok for a +40mn session!
