Conrad- all the appropriate superlatives have been used. All I can say is that I can't imagine one image of this incredible action being any better than the one you got.
As a non-motor guy, I have a question: wouldn't your reaction time for that first pressing of the shutter be a major factor here? Also- with your unbelievable skills, I can easily imagine you getting this same shot with an old non-motorized camera. One click- one perfectimage.
