I've been doing a fair amount of research regarding sprinkler heads and by far it seems the Hunter MP Rotators are the favored head. Just for discussion sake, what other heads have others used that they like or don't like? I currently have 2 Rainbird 32SA spike sprinklers and actually like how they work and put water down, now I have no clue if these are bottom of the barrel cheap heads or not. Just looking for insight as I continue to research my future sprinkler system!
