Injector question/comparison

Hope to see the results, I have mahle marine pistons in mine that smokem recomended awhile back.
 
From my understanding, (not saying its true) I heard on bigger injectors, like 5x.018 vs 7x.015 the 7 holes perform better on a 12mm pump cause they keep pressure up for atomization?
 
Hopefully smokem can comment on that, im going to finish the year with a 12mm pump. I think were going to try a 13mm pump on dads truck for sure next season and go from there. You have a 13mm on yours murph? Or you were going to one I think I read?
 
I'm going to one on "The Project" flown to 650-700 and set at 530-550cc. With these injectors and my current Turbo with a 50mm gate.
