Go ahead and try the Bolly just to see, prop selection is kinda a trial and error type deal to find what you like, the only thing I will say if it is a carbon Bolly (they make wood now too!) you will find that it will take a while for the engine to "spool" up and down because the Bolly is a solid carbon prop, so its heavy. I have always found that when you go up in diameter on a similar type prop it will load the engine more than if you go the same step up in pitch.
