I have the older Seek Eolus with nest. Love it for solo stuff. Zipperless doors are no trouble for me. I can't quite reach it while laying in my bag but I'll get up, get boots on with my feet in the vestibule, lean forward a little and raise the door. Pitch does matter a bit, if you are too tight the zipperless door obviously won't come all the way up. I've honestly never found it to be an annoyance though. Get one ans try it out. I doubt you'll be disappointed. If it's not for you, it'll be easy to sell here.
