If cheek puffing is s problem it doesnt happen with a fitlife total face. Pressure is equaled over the entire face. They look huge but honestly are a very comfortable durable mask.
Hoping if I can catch the mouth leak early (via the Hybrid applying pressure on both fronts - well front and back actually - regarding the tongue seal) that it won't be enough of a leak to cause puffing. We'll see what happens in actual practice...
I learned a couple of new things in the past day. One - as I start drying out, it gets harder to get and keep a seal - last night I drank a little water every time I woke up with a leak and dryness - and that helped (a little). The other thing I figured out, while sizing for other masks, is I got the wrong size for the Quattro Air that I used the first week. I got the medium and should have gotten the large. I might have printed the sizing guide with scaling on instead of original size, or I just misread it in my sleep deprived state while starting this process. So that probably helps explain why I had pain and leaks with the Air, which led me to convert to the P10 pillow.
This morning I started to simply order a large cushion for the Quattro Air, but also found out that the mask frame is a one-to-one size match to the cushion. While the F10 which uses the same cushion will use one mask frame for both medium and large, the Air does not. Since I already have two more masks coming (the Hybrid and the Forma) I am going to hold off on replacing the Quattro Air (for now). But that's still an option I would like to revisit at some point.
