We are definitely moving forward!But since we are all different in that regard, I don't know that we get to anything ideal. But yes, for realism we want some deformation of the cheeks which none of these HATS have. Until a couple of years ago we didn't even have flexible ears! That really screwed things up.
I think part if the Abyss pitch is that rotating the pads should help accommodating different head shapes and so on.
That said, I definitely understand that a lot of time was spent trying to get a good fit on the rig.
Maybe when the other set comes in you could try that and see if that changes things.
