One night my AHI <1, and other nights I have AHI 8.0+. I am uncertain where this mask is leaking when I'm asleep. I use a ergo neck pillow and ResMed Narval CC dental appliance as well as a chin strap since I mouth breath. The problem I think, is I have a wide mouth and the AirTouch lets air leak from corner of my mouth if I mouth breathe. So I need a wider FF mask at the bottom of mouth.
My DE had a poor selection of masks to choose from. I've tried these masks:
AirFit F20 - I used in the past, and I had to tighten too much to prevent leaks, and it made red marks on my face.
Quattro FX - This fit ok I think, but it is less convenient and doesn't have magnetic closures, and not a good headstrap.
Nasal Masks - Tried numerous, but they all leaked during the fit test, and the DE said they didn't recommend them.
Good luck on that one, as everyone is different it is very difficult to give advice on a FFM or Nasal Mask for that mater.
Nasal Pillows is another mater as they come with usually three sizes of pillows and then some have larger or smaller ones you can order.
As you have found out, it is not easy to get a perfect FFM or Nasal one without some leaking.
I have never found a FFM or NF that didn't leak yet.
I wish someone would set up a full mask fitting service.
We have a company here in the UK that will allow you to try if you visit the shop, but it is a long way away from me, for the UK it is a long way.
We put in lots of roundabouts and traffic lights and bends on the road, then fill the road with far to much traffic so it take forever to get anywhere.
Have you considered a hybrid mask? This is just another option, if it leaks above the mouth anywhere, this might be an option.
There are a few around these days, I would love to try one, but my clinic say it does not stock them as there is no demand!
They have never stocked them, so of course there is no demand!
I use Nasal Pillows, but I get air leaking through my lips, chin strap or not.
Good luck with mask hunting.
