You can see all of that on the arrl mast software at a glance.  Huge difference 
in strength.


All quite true.  One possible argument in favor of a 2 inch mast
has to do with stiffness.  The large diameter mast will be
considerably stiffer, and will not provide as much "shock absorber"
function to protect the tower and/or rotator.  Just
playing devil's advocate.
