I certainly didn't help things regarding your understanding with the  
initial post I made.  My concern was for the edge support options for  
whiffle tree cells (other than, as opposed to, and as options to the old  
sling), but I confused "edge support" with "whiffle tree".  I now believe  
the term whiffle tree is more related to the multi-layerd / multi point  
systems of mirror support built atop three adjusting points, and that it  
is not particularly concerned with the edge support method employed.  Your  
trinagle/bar assumption is correct for whiffle trees.  A few readers saw  
through my confusion and offered edge support ideas.  More edge support  
ideas are welcome!!!
