I would be shooting DX only for reach and file size.
Evidently it will not lock on a moving object better.
4fps is what I have used for years, it used to be 3fps
because I do not like getting two shots when I only want one.

At the start of a race is when I want more than one shot at a time.
4fps is more than fast enough for my use.
The only time I would use (CH)11fps would be either to show off or show up a Canon shooter.
I actually sent one of my competitors home by doing that, when he tripped over his ego.
