I'm trying to choose between the Exped UL "medium" and "large" air pillows. There is only a 0.3-0.4oz difference between them, so I'd rather pick for comfort. I'd be using one with a regular sized Xtherm, which kind of tapers down at the head, so I'm not sure which would be better…is there anyone currently using this combo who can comment? I'm a side sleeper for what it's worth. I've never used a real pillow, only a stuffsack with clothes, but I've gotten UL enough that my clothes don't make a very good pillow anymore…
Also, have you found you can effectively tie the pillow down to the Xtherm despite the taper (any pillow)?
Thanks!
