More smaller holes don't always equal better atomization.
What works really comes down to trial and error. After somebody does find something that works it's explained with terms like "spray angles", "hole geometry" and "injection pattern", but it's more of an art than a science.
Furthermore, injectors that atomize really well in some heads and pistons might not work worth crap with different swirl levels, valve geometry or piston design.
Hmm... Why not cut a couple really big holes in the very middle and then a few smaller holes around the outside...
