36 Front and rear. 3 cross. 145# rider 40# bike. Wheels have never been trued in >30,000 miles. *shrugs*

Are the wheels straight? No, probably not. With a roller drum rear brake and a nearly dishless IGH, I don't really care either. The front? That's a rim job. It matters a little I guess, but as long as the brake doesn't drag I don't really care.

Tension? I just checked the wheels in a few place. I thought I found a loose spoke, but it was just a fender stay.
It certainly isn't a TIGHT wheel, but I'm not getting any spoke punctured tubes either.

Heavier? yes. Does that really matter? I'm sure my insulated coffee cup slows me down more than the 8 extra spokes.
