Fine pitch is like a low gear the plane will climb better accelerate better and so on, that's why planes take off in fine pitch then go to course for cruising speed.

with all do respect, I can't agree. speed is the result of pitch AND rpm. A 2-stroke turning the same diameter prop with far less pitch at far more rpm can be going the same relative speed as a 4-stroke with twice the pitch yet half the rpms, but both engines will be their power zone. have you ever heard of a constant speed prop? It is all about pitch.
