Vicen, that is hard to answer. Most of the props are good, but there are many variables at play here that there is no simple answer to your question.

Depending on how you have your sleeve and head settings, the elevation you are at, pressure, temp, etc... Its very difficult.

Just about all the props can be made to go fast depending on the motor, weather, and needle setting.

You just need to do some research and keep good records.

the profi motor was pretty similar to the Nelson SS. These props worked best with that motor for me.

8.8" x 8.75 just about the best all around good prop.
8.8" x 9.25 fastest prop under the right conditions, it needs to be a strong motor, and launched a little richer.

My Profi tended to take about 300 ft to get on the pipe and about a lap and half to really unload on 8.8/9.25. After it was well broken I settled on the 8.8/8.75. I settled on a .005 in for a head shim.
