They do match the precip rate...they fill in the area the 3000's miss. I have used several bags and like what I see so far. Converting smaller neighborhood parks one at a time from the old maxi-paw for better coverage. The PRS40 6" heads with check valve are more reliable and easier to adjust than the rotors too.
They will be coming out with an MP800 soon to fill the 8-10' range.
