So the title is dumb, but this is a clear and straightforward question. I'm rebuilding a wheel with a used hub, whose bearings are in very good shape. Now, the spokes have "worn" into the hub flange, seating themselves and creating little groove-depressions in the aluminum. When rebuilding the wheel, should I place the spokes exactly where they were the first time around (so, the new spoke seats in the same little depression in the flange) or should I rotate things so that the new spoke is against a "fresh" section of flange? I can imagine arguments both ways, but probably there's some consensus. Thanks.

I would lace it up the same way as before. This is the only way I've ever done it, so I can't say I've tried it both ways and have learned from experience. The spokes just look like they'd be happier in those grooves. Plus, if you make a mistake lacing, it is immediately obvious.
Lace it the way it was. If nothing else, the hub will look nicer.

Alternately, the question could be phrased in the following way:
* since flanges never break, the main issue here is whether a spoke will experience less (detrimental) stress by being exactly where a previous spoke had seated in, versus a spoke-hole that hasn't been used at that angle before
* this is somewaht similar to asking if a spoke will be less likely to fatigue in a new hub as opposed to a wheel built on a pre-used hub with the spokes in the same place as they were the first time the hub had been used.

I'd be concerned about the inside of the spoke hook rubbing against the "worn" area or sharp edges if you reversed the lacing.
Personally, I'd lace it exactly the way it was before...
It make no difference apart from cosmetically. I've rebuilt hundreds both ways. None have come back with the flange or spokes broken.
