Years ago I switched from rotary heads to RainBird spray heads. Depending on what coverage I need, I use VAN 4 to VAN 18 heads. All are adjustable to 360 degrees. My pop ups are 4" with a 1/2 inch intake. Unless you have a very large yard with low number of heads, these Rainbirds should work. You can order directly from Rainbird.
