Pauter's description for why their rods work:

For starters, the simple beam design completely eliminates thin and non-uniform cross sections over the total length of the beam. This feature greatly improves resistance to crack-induced metal fatigue. In addition, the non-tapered profile of the beam helps to spread potentially harmful stress over a larger area, dispersing instead of concentrating these destructive loads. The design also efficiently places needed material in critical transitional areas, giving maximum support exactly where it is needed (such as directly under the wrist pin). The streamlined contour also provides subtle benefits in the form of windage reduction. The main beam rib itself continues around the wrist pin boss, perfectly integrating the beam to the pin boss, a small, but important contribution to overall structural unity. Pauter rods are indeed, different by design.

EDM pressure-fed oiling to pin available at extra cost, but not necessarily recommended.
