Thanks! Yes, a little play to account for the QR's is what I'm going for, although that isn't the case on my other wheels (or barely perceptable anyhow).
I redid the front wheel today and also did the rear wheel. I spend a lot of time cleaning both the races, inside of hub ("flossing"), the hub axle and cones, but somehow it just feels like there's a little bit of dirt in there - both of them - same thing on the rear wheel. However, I don't know what level of smoothness to expect, but I have other wheels that are 40+ years old that are smoother (that I have never repacked).
I don't know if the likeliest explanation still would be dirt inside the cones, any imperfections in the races or something else? Wheels seem to be in perfect condition otherwise. All input appreciated.
