If you can field 8 shots exactly like this then you can tell me what I do or don't need. That is a very rare score and an extraordinarily difficult score to capture in a way that proves it even happened. I am told that no one else has ever captured that score the way I have, much less a stack of eight.
The mathematics behind that sport demands a minimum of 8fps for any chance for consistency in capturing the peak instant. Eight isn't really enough; it is bare minimum to accomplish anything. Some of those peak instants in time occur within as little as 1/30s.
From all appearances Nikon is eliminating a tier, which happens to be my tier. If they eliminated the D4 lineage you would not be waxing so philosophical about these things.
