Hello from Belgium,
I have an air2 since a year, and bough all types of props for the fun of it, and polished them all gently to be really smooth..
Vindibona1 is right, the MAS props are quieter, and bring a lot, but for slow Motion filming aso, they can be tricky to keep the dorne calm.
When windy, or tree environnement, I use carbon props - solid and stable to flexion, the flight is also slightly smoother (okgogogo store on Aliexpress)
Standard props are just perfect, but when security is needed, I use cheap red props, also bough from Aliexpress, and they do the job as well.
Will try the new release with 3 props
