250mm will cost twice as much for nozzles and is overkill.
Very good point. Also, make sure you are aware of what type of tips you'd want to use prior to buying the bodies, as there are differences in how they hook up.

If you are putting new bodies on the boom anyways, I'd probably recommend top-fed bodies so that you never have to worry about air in the boom at all.

What is the optimum spray height for 20" (500mm) spacing? like two feet. Who can consistently run a sp sprayer in any rough ground at that height? I have spent extra money eventually to go to 30" spacing. Good coverage at realistic height. Large tips that resist plugging. and Less tips to buy. Just MHO.

If your boom is plumbed for 250mm spacing's then I would be using those spacing's. Main reason is its much easier to decontaminate if you are using all the outlets.
I would also second this. I bought one with 15" thinking I could use half of them. Wrong. They held up product in the off nozzle bodies and eventually started rotting out the diaphrams. I have them all pugged with a chunk of rubber now with a hose clam.

Most Nitro's I have seen in Australia come with the 250mm spacings.
As far as boom height and choice of nozzle that is a non issue but Yes you obviously have to run smaller sized nozzles.
Theory here is still run the boom at 500mm height and get twice the overlap, still use same angle jets. But if windy and good field then can drop boom to 250mm and still get proper coverage.
It depends what weeds you are targeting, standard is fine for largeish weeds but often we chase very small 2 leaf ryegrass and the 250mm spacings works very well especially if there is lots of stubble.

We don't have too much high stubble to worry about, I know in Aus they usually treat the soil a little more than we do here so it is a large issue of getting the actual ground treated rather than having the chemical hit the stubble and do absolutely no good.

Had a fellow who was actually going to try get 30 degree tips at 250mm spacing because he did the math and he will actually get better ground coverage at the shallower degrees than he would with a 80 or 110 degree tip. Keep in mind he would be spraying through stubble that was like 300mm high.

We run our nitro with 250mm spacings. In windy conditions nice to have boom closer to the ground. Also at 250 mm we can run higher water rates still with good good speed. In summer we have the option to go back to 500mm and run 40 l/ha at 30 km. (dust permitting)
