    A two bolt block is stronger than a 4 bolt in the webbing. A four bolt was designed for extended running at above 7 grand. They were installed to keep the cap from walking. The thicker webbing in a 2 bolt is thicker and will handle more stress than a 4 bolt. Meaning it is easier to push the webbing out of a 4 bolt than a 2 bolt.
