Default Prop for K&B 7.5 DF on Diamond Dust

I have a Diamond Dust with a K&B 7.5 DF with a pipe. What prop would be a good choice for max speed?

My friend Guido has the same combo and is running some odd size APC 8.75x7.25 I belive, I prefer the 8x8 apc myself, but my DD has the MVVS .40

I am currently using an 8x8 apc. Anything in this range should work. The front carb version likes high nitro 30% or more.

15% should work fine as long as you use god fuel with enough oil. I run Wildcat Jet-A ducted fan fuel.
