I’m on the Alu version of that at the moment, with a mixed build of X0, Avid Juicy Ultimates and XT chainset. Same fork (Bar the colour!) as well.
One thing I have found, and you may as well, is that this is a bike that really benefits from a Pure/Joplin type dropper seatpost (is there a term for them yet?) as it rides so well on the smooth and ups with saddle up and even better down with saddle down. Worth trying, IMO.
Depending on where you ride, you might be a little under-tyred as well, if you ask me. I’ve got big up front, Rubber Queen 2.5, and a Spesh Eskar 2.3 on the back.
Oh, and WIIIIIIDE bars work really well on these at speed/trail centre type riding.
