Mine has been ok on the two rides I have done so far. There's no noticeable play in the headset when properly tightened or judder when braking which would be the signs of a poor fork/headset interface.
The last Colombus fork I had had slightly misaligned fork tips which put the wheel a few degrees off-centre.
Doesn't the minimal require a crown race? The Hylix forks have an integrated bearing race, I'm using a CK Nothreadset with mine.
