Thought provoking thread! It led me to read about rating factors for hitch pins

Hitch pin attach point - - - If the strap is pulled at an angle the load on the pin is uneven so a hitch pin should only be employed for a straight pull. Pulling at an angle can also cause chafing of the strap against the edge of the receiver.
Bow shackles' curved surface allows a wider variation in safe pull angles
Many times it is difficult to set up a recovery for a straight pull
Some hitch shackles are drilled to allow vertical and horizontal orientation for more versatility
