Most suggest a prop of 9450. These can come in various styles and many like the 'lift-boost' Phantom 3 props.
I am unable to post direct links but will post not as a link(hope this is ok)

I have used these and found them to be pretty good, cheap set. May need slight balancing as do pretty much all new props, and the 2 with the black aluminium centers may be a very tight fit due to the black coating on them. 5 mins with emery of small file will help them fit easier.
I may try some carbon nylon props of 1045 or some 9060 to try a improve flight time and vibration.
