B&W Companion vs Andersen Ultimate Showdown!

Tried to get an ancient Egyptian pyramid architect to comment on the basics of why their structures are still standing and will for eons after we are all gone to live on Mars. Or if you like something more current you can look at the attachment points on the 747 plane that carried the space shuttle all of which are a version of the Andersen ball and triangle design. Not sure, I could be wrong but I believe these people know just a tad bit more than anyone on this site about loads and strength.
I`ve commented before and any snap jaw hitch is a disaster waiting to happen and is going by the way side after this generation of old fogies retires out.
Hope the picture posts, here goes
