I tried the P10 and had problems with something on the headgear digging into my cheek. The headgear was too tight with no adjustments possible. With your head issues, you may not like this.
I used the Swift LT for a while. It has a low back strap but the placement of the pillows is not overly dependent on it. I don't have any memory of it causing pain, although I did have facial marks on my cheeks. No tenderness, just marks.
