Propeller choice for 115S

Hey fellows! I need ideas for prop size on a 115S. Theres plenty of info for a WS version on high nitro but im looking for stock plain jane sport specs.
I want to run on 20/20 blend. For best pull for stuntplanes e.g. I use a 16x6 on a FZ-1.10.
Im thinking the right one is 16X8?

On the other hand what do you guys like to use for high speed and pattern planes? 14x....?
Please keep in mind im thinking of a plain S version on 20/20.

14x12 on 20% nitro is about right. For a scale airplane I think you could get away with a 16x10.

FWIW: I fly my Silver Class Warbird racers utilizing a 115s with an APC 14 x 12N prop on anywhere from 20 - 30% nitro, and 20% oil.
