[ATM] Whiffle Tree mirror edge support help needed

[lsayre at neo.rr.com (Lawrence Sayre)]

Can anyone point me to good examples of Whiffle Tree based mirror cells?   
Sites containing pictures would be great (I often get far more from a good  
picture than I do from a good dissertation).  Is there any consensus  
building yet regarding the advantages of this type of cell as opposed to  
the old sling, as regards astigmatism, etc...?
