Resmed AirFit F30 FFM

To OP - I wonder if the F30i (the model with hose over head) may work for you. Can't think if a good reason why -- but then again -- may be worth a shot. My mother used to say "if something doesn't work for you, try something else."

Yes, I am going to try the F30i. I'm due new supplies in a month or so. I can switch back & forth when it comes to masks w/o any problem.

After many years with the Mirage Quattro Pro, I tried the F30 this year. I have a short beard and moustache, so was apprehensive. The F30 turned out to be a very good choice. But like all masks, they fit great sitting up with no hose attached
I get annoyed with leaks they are all due to body movements/head position. Body movement creates even slight changes in hose position. It is a big lever applying force on a very delicate seal surface. I have procrastinated about making or buying a pre-made hose support - recently reviewed. 
I also wonder if our brain is in a different sleep mode if we are awakened than when we first go to sleep. If a mask leak (ie external noise) causes us to awaken after a short period of sleep do we awake in an alert mode? We are not relaxed, the brain is quite alert, a bit of adrenalin? Makes it hard to relax and drift off again. 
The mask is only one of many parts in this puzzle.

Agreed.  When I first got cpap, I tried on a couple of masks at the DME .. sitting reclined in a chair.  At home, in a bed, it was of course a different situation. I ended up changing to an F30 and it's worked very well for me.
When fiddling with strap interrelationships and overall tightness of seal, it's important to "relax" facial muscles (its harder than it sounds) and of course try different head and hose positions.  
People with higher pressures have a harder time with this, trying to balance comfort with leakiness.
