<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Pauter has been making this design for almost 30 years with zero cold failures. If it were a poor design they would have changed it out of necessity. According
to a Pauter rep., the main reason they started manufacturing their own rods in the first place was due to the fact that the H beam and I beam rods they were using couldn’t put up with what they were throwing at them with their turbo charged 4cylinder engines.

This type has no material were it needs and too much were it doesn't make sense. Maybe for very short rods usable.
