The new Tektro front hanger looks promising, I'm guessing that the bolt and nuts hold it tight against the fender mounting hole in the center of the front fork. To my eye, the advantage of the rear hanger is not so clear--it looks to me like it will stop the cable in the rear at about the same place as the Surly hanger, which may be more adjustable in that you can rotate it forward or back.

I'm using this clamp with the Surly hanger (and the Nashbar Cross frame):
