For the Zonda I had great success using the 1816/3 blade props from Dasbota. Picked up 6 mph overall.

The Zonda, same motors and ESC's you list with 5s 40C batteries and the CNC 45mm props (1.4 pitch).
I also like the Octura x642 prop. I use it on my 29 inch AquaCraft Motley Crew, 2200kv motor, 180A ESC on 2x4S (parallel) and 36 in Genesis with a 1600kv motor on 2x6s (parallel).
