I agree with Larry. The 2-blade should be more efficient if it is pitched right. However, one benefit of the Warp 3-blade is that, if you have the time and patience, you can adjust it until it is pitched right (overall) for whatever you want, be it climb, cruise or whatever. And if you make some aero improvements to your plane later, you can add more pitch at no cost. On the other hand, the amount of twist is always the same (just like on a constant speed prop). There's almost always some compromise. I'm quite satisfied with my Warp 3-blade prop, but I have to admit that I wish I had a 2-blade prop, every time I start my A65.
Look at data at http://www.krnet.org/kr-info.html to see if your prop is in the ballpark.
