It is quite a comprise on any airplane capable of 200 plus miles per hour. If you pick a pitch that gives even acceptable takeoff performance, you will not be able to pull 75% at 8000 without excedding the recomended cruise RPMs. If you pick a pitch that alows you to pull 75% at 8000 at 2500 or 2600 RPMs you will have very poor takeoff performance. With a constant speed prop you get the best of both worlds. GO FOR IT. Tom Byrnes N133TB
