I assume you are installing the sprinkler system yourself???
Iam an irrigation contractor and i use the following items for my instllations here in NY, but it may be slightly different depending what is available in your town.
1. Rotors - The HUnter PGP (higher pressure) and T-BIRD(lower pressure, these heads are pressure sensative)
2. Sprays - Toro 570
3. Valves - Irritrol 2400T (they are so good, these are the only valves available here)
4. Controller - Hunter SRC
5. Oietker Clamps
6. 1" Pipes and Backflows
Have a contractor pull your poly pipe. It cuts down time, digging, and damage by (75%)
As far as exact type of sprinker heads, i need your GPM and PSI
