I ended up getting the Cutthroat. For me, it made the most sense in relation to the other bikes I already have. I am in the same boat with what bike to use on the colorado trail. There are advantages to the Cutthroat (the detours around the wilderness areas) and advantages to a full-on mountain bike (the techy singletrack areas). You just need to decide on what advantages mean the most to you. I have checked out so many bag options that I feel like I have too many good options.
Ride safe out there!
