Kings on Stans Alpines have been fine for me.
I had a King/Kong Superscharf wheelset, the front hub was fine, but the Kong Superscharf was utter toss! Fell apart in spectacular fashion, and then weren't user serviceable, so I had to unbuild the wheel and return the hub, happened again 9 months later!
I think they have now made them user serviceable, and it's not a problem on the standard aluminium axle hubs like the Kong, but it put me right off Tune
I also have a Tune Prince/Princess. The Princess front have been fine but the Prince is on it's third freewheel and second axle in 2 years. This is not user-servicable (Poshbikes damaged the axle getting freewheel off!)
