best heads to use with fertigator

[KDLAWN]

I have been looking at installing fertigator on several of my installs coming up and was wanting to know if there was a certain kind of head that works better that another for the application of fertilizer through the fertigator.. I use 3 type of heads.. One is rainbird ( Impact Rotors ) and hunter (Closed Case Rotors), and the spray heads.. Seems like I would get better coverage with the impact rotors and spray heads, but would like to know what your field test have shown

I recomend the Rainbird 5004 rotor head. Best head for even coverage and matched percipitation.

And that is based on what criteria?
