Thanks Mike K. for a good summary of action shooting options:

And some of these will more likely give you PSA award-winners than 
others!  The Australian legend Allan Griffin pioneered action 3D with 
twin SLRs, longer lenses and wider bases (PePax? Ouch!).  RBT is not a 
neat tidy version of #1 since it is limited to normal base.  In most 
cases the action is far away and twin SLRs with longer lenses and wider 
bases is the way to go.  I have seen Griffin's amazing award-winning 
pictures, have read his many articles in Stereoscopy on selecting/
testing twin SLR systems and have tried to duplicate his work by 
shooting in Sea World with some minor success (only acceptances, no 
awards!) -- George Themelis
