My favorite sport props are the Bolly Clubman series.

They offer more static and dynamic thrust than the other makes.
Compared to comparable props from APC and MA, they produce better performance, despite the lower RPM, from their +1/2" diameter.

They survive minor ground contact without adversely affecting their performance.
In addition, they are only marginally more expensive than MA.

The APC props are efficient and produce good top speed, but ANY ground contact can spell a new prop and they cost more.

MA standard (up to 11") props produce less thrust, but withstand minor ground contact. But despite being minor, the slight tip damage has a profound effect and reduces thrust very significantly; much more than in Bolly props, where it isn't noticeable.

...Yes Dave, the tip produces most of the thrust in MA props. In Bolly, it is probably the 70-80% station.
