Looking at changing masks Opus 360 to ???

[spotteddog]

I chose an Opus 360 for my first mask. I like the idea of the nose pillow and it work OK only problem is the headgead doesn't go far enough down the back of the head or below the ears and it slips off the top of my head enough to let the pillows slip down. I wake up 4 or 5 times a night to adjust the headgear and back out again. So now I'm looking at the headgear before I look at the mask to see if it will work. I like the looks of the Wisp. I see it has 3 sizes in the box so it should fit. Also see there is a large headgear available if needed. I do sleep on my sides and once in awhile I wake up facedown. Any thoughts?
