I have a foam pro 12 that I basically converted to a multi by making it not foam. It worked really well for rinseless prespraying except that I would go through about a whole gallon of solution per prerinse. I decided to try out using the multi pro 12 nozzle on the foam pro 12 and it really helps stretch the product more. I am able to do 3 cars or so with just a half ounce of rinseless to one gallon of product. I also like the adjustable pattern so I can get extra pressure if I'm not using a hose or can do just a light mist before drying.
