Short radius I20 vs PGJ

I'm in the process of designing my irrigation system. In total it is about 13,000 sqft, with the bulk of the radius for the sprinklers being being 18-30 feet.
With my goal being long-term reliability, should I go with I20's over the PGJs, or make it easier (and cheaper) on myself and go with the PGJs?

Thanks wetboots! That is the way I was leaning, but wanted the confirmation.

Rotor heads with 3/4-inch connections are going to be more durable. The only popup rotors with 1/2-inch connections that are likely to become commonplace are the MP Rotator types, which would fit your application, given the shorter spray distances you have.

I'd put a sprinkler at 2:30 pm of that top arc. I see a brown spot happening there.

Where there is only single coverage from the smaller full circle head? I'd lose that full circle in favor of a half-circle on the border, completing a head-to-head layout on the back border, and maybe alter the half circle next to the "future driveway" into two part circle heads next to each other, with their total arcs making for the same half-circle arc of the replaced head, and with one of the heads having increased distance, to reinforce coverage where the full-circle head was removed.

Thanks WetBoots and MrFixIt. I have made adjustments to resolve the dry spot
