Suggestions for small lawn strip irrigation

Have a lawn strip separated by a five foot cement walkway. The width is 5 feet, and the length on the left side of walkway is 15 feet, and the right side 20 feet. So the lawn area is 5 feet by 35 feet. Have dug a trench in the center the complete length and under walkway. So the trench is about 40 feet long. The water pressure is about 30PSI for this zone. Having trouble deciding on how best to irrigate. Will the Hunter MP strips work here? Both Toro and Rainbird strip nozzles only do a 4 foot width. Maybe I should just use 5 foot fixed sprays. If so, would triangular spacing work?

Could extend the right side from 20 feet to maximum of 22 feet.

Rainbird also makes a 9 foot sst that can be turned down. Upper

If I used the Rainbird nozzles, could use 2 15ESTs on the left, and 2 9SSTs on the right reduced down to 5 x 10 on the right if they reduce down that much.

I would still use one in the middle for double coverage and cut the minutes....Upper

Hunter has spray head strip nozzle's (not the mprotator strips) that do 5'.

Think I would need to use to many heads with the 5' fixed sprays.
