Personally, I’ve used the hose and pressure nozzle since I saw the technique demonstrated by Emil Bossard in a newsreel back in the 60’s. It’s a great technique, but there’s a lot more to it than blasting the soil mix out of the grass. You have to be very careful not to blast the soil from the roots. If you do, you should top dress them with a little sand to keep them from drying out in the sun.
By far and above, the best way to keep getting LIPS to a minimum, is to never allow the drag within 6” of the grass if its dragged by hand, and never within a foot if its dragged by something motorized.
No matter what you do, minute particles of soil will kick up when the drag is pulled, and the faster you pull, they farther they’ll fly. Having the soil damp will reduce the amount of soil that “flies”, but that also makes the drag much harder to pull. Couple that with someone not paying close attention and actually allowing the drag to touch or get up on the grass, and its easy to see why the biggest lips are usually on the corners.
