I'm redoing our backyard sprinkler system because of a big patio project. I sent off our landscape plan to Orbit for their design and they came back with the design shown below. Seems to utilize a ton of smaller sprinklers and some could be removed by using larger rotors, but I'm not a sprinkler guy. My neighbor works for toro and can supply me all their stuff for free so I'll chat with him but wanted to get another opinion.
