Ok, so it is a no no. but, it seems like the math could be done to figure out if you ran a walla walla spray with some i20 nozzle you could get it really close. I'm assuming that you would run head to head. Goal would be to figure math. any thoughts? Application is that I have a mobile home park to install the complete, from scratch system in. By far I will have a BUNCH of sprays, which the walla walla solution with between homes. But, there are some bigger areas where it would be nice to use the larger radius sprays. thanks.
