Velocities are really good stuff, and are actually based here in my town. I've dealt with them a lot and their warranty service is phenomenal (walk in with a bad wheel and walk out with a new one, or they build you one that day). One of their wheelbuilders has built a few sets of wheels for me and running their cheapie Spartacus wheelset, I have only had to true them once, and it was after I was launching my roadbike off of curbs and speedbumps. When I build a 29er I'm probably going to use Velocity Deep Vees or something similar since their wheels have been very reliable for me and a number of others I know.
