The configuration of the hanger shouldn't matter at all. The bolt is a pivot point for a beam to reach the rim at several points around its circumference. The distance from the beam to the rim must be the same at all points. To do this the beam must be square (or at least consistently angled) to the bolt. How you make this happen is strictly up to you.

I recommend you take it to your LBS and have them show you what they do to align the hanger.
