I find that too limiting as I use a P10 and I do not tighten the strap at all so I like the excess of the hose running from below & up vertically to my face, this allows me to sleep on either side, back, or front with less pulling on the mask.hang it over your bed frame or put up a hook so it hangs down above you instead of having you snuggle it hahaha. the hose cover makes a difference when i do run water in my machine. i also have the air sense 10.
I did try the P30 with the connection on the top of the head and I did try the hose overhead with that particular mask....this worked well like you say but I did not like the extra straps and how the mask hugged my temples so I won't use the P30 for that reason alone.
The P10 feels like you're naked compared to the P30. I like that much better as it is the least bothersome to me and I have had the most success wearing it because of that.
