The other issue at play here is that skinny triangular supports demand 
careful/accurate calculation of the balance point, and then proper 
fabrication/location of the hinge/pivot.  If you don't do that...you won't 
have the desired balance forces on the support points and your mirror's shape 
will suffer.

This is why it is a good idea to have your triangular support points arranged 
in a more 'equilateral' manner if at all possible.
