I'm also looking at the LS Batura, which would be warmer at 5500-6000m?
Yes, I have them, and dearly love them. I wrote a review on Backcountry:http://www.backcountry.com/mammut-mamoo ... -boot-mens
In a nutshell: warmer than the Trango GTX, about as warm as the Nepal EVO but not the Batura. Fit is very true to 'real' size (eg, fairly tight) so they excel at waterfall ice climbing and mixed, but these are not warm enough for big ice peaks IMO; for rock or mostly rock to 5000m they would be excellent.
