Help with P30i mask

[NevilleW]

I've recently had success using P10 (doesn't cause random frequent arousals anymore with better pressure settings).

The only reason why I'm interested in the P30i is the the way the hose is connected up top.  I dislike the front connection with the P10.  I like the very minimal feel of P10 however.  Not sure how well the P30i will stay on my head since I side-sleep.  I'm not sure how well the silicone frame works for air delivery when side sleeping.  

Any comparison with P10?  Why one is preferred over the other?

The frame is double sided so if sleeping on your side & pillow side of frame crushed it just pushes air via the other side.
I haven't found any issues or air supply restrictions personally.
