Agree with @hsvtoolfool , strip nozzles are just never well characterized in the spec sheets and it's impossible to design a system without actually trying the different brands in an above ground test layout. I've thrown up my hands and only use them on beds. I use Hunters. I have had good results on long narrow beds with them.

If close enough is close enough, I'd go with Hunter SS530 and RCS / LCS 515 in a triangle pattern, in other words space the heads 25' apart (always derate the throw in the sell sheets) on either side of the strip with the heads on side A directly between the heads on side B. Your precip rate will be on the order of 2" per hour (if I calculated the flow rate versus area covered right - I was where you are a while back but I remember doing the calcs and I think I did it right). For the Hunter nozzles, the ends on the head side at each head tend to get more water than the middles but by opposing them this way it should all average out close enough, at least to keep the grass growing.

Messing with the screw on the Hunter side strips doesn't do anything. I don't know about the center strips but you may have been wasting your time with that.

If it absolutely needs coverage and a zillion heads and overspray is not an obstacle, maybe take a look at the Hunter microspray nozzles.

To go off on a tangent, I've used the MP800 line on turf strips but the strips were around 10' wide. For a 5' turf strip, that's always a head scratcher of a problem. For wider strips where you can use them, the MP800's do seem to provide much more even coverage than any other typical nozzle.

I've never used drip lines so don't have a clue about that. Does seem to make a lot of sense if overspray is verboten.

How I ended up a while back actually solving a problem of a very narrow turf strip - irish moss, green carpet grass and ajuga.. :lol: They all spread and after a short time, weed control is not an issue.
