Good choices. I have Arc 27, and at times wish the tire footprint was a little wider (running 2.6/2.4), but are reasonable light (around 1750g wheelset DT350 hubs) and have stayed true through my hack riding.
No $800 / rim carbon super rims? This is bucking the trend of the must have carbon mantra in the industry. There are lighter out there, but who wants to be constantly worrying about blasting apart a wheel at every hard impact.
