Just to give an alternative opinion, I work in SI (obviously, though) and have a hard time dealing with the customary system. You have been raised in the customary system as I have in SI, so we have kind of a 'native' understanding of our native measures.

just "stirring" things up...  The SI system has it's merits.  Sometimes it gets lost amongst those of us that work exclusively with in-lb imperial units.

There are a few things that I don't like about the SI system but I don't think antiquated is one of them, unless of course you're just trying to stir things up.
My biggest beef is with millimetres; gives you numbers several inches long.  Occasionally, I see calcs from Europe and they are still using centimetres, which seems a lot more sensible to me.

That, I believe, is what happened.  Winds of 30 MPH (= 48km/h for those who use that antiquated Systeme Internacional unit system...  :-p  ) on Monday night and early Tuesday morning apparently caused an imbalance in the tie rod repair, and snapped one rod.

I hope I am reading this right, but it looks to me like the tie rods are ending well above the pin.  This to me is asking for trouble. Any slight eccentricity or lateral load will tend to de-stabilize the saddle.
