The bombtracks look nice too as far as the bb, gearing, cage mounts, etc. Looked at the beyond a while ago, and they are a little bit hefty at 27.5 lbs.
If was I buying something today, I think the Norco XR S2 would be a strong contender, though probably a compromise because of weight (yet still pretty good at 6lbs lower than my current bike).
The Salsa Cutthroat GRX 600 would be ideal, but I don't know if I'll get to the point where spending that kind of money is feasible.
