Default H9 20cc mustang propeller choice

I have a 20cc mustang with an OS GT33 in it, and I need a propeller. What do I get? Speed is No1 priority as I want to see how fast this thing will go.
Suggestions:

18x10
19x8
20x8

any inputs?

Smallest diameter and highest pitch gets you more speed however you need enough diameter to overcome drag. The 18x10 will be a good starting point. Also keep in mind the the smaller diameter will mean lower acceleration rate. Brand and material the prop is made from will make a big difference as well. Wood props tend to flex and decrease in pitch with rpm, carbon fiber props are your best bet.
