Hi Steve,

    I had a Swift a number of years ago and discovered after trying several propellers (all of the metal propellers available) that the Sensinich propeller gave the best all around performance.  Assuming that they have not changed the design for the worst, it is an excellent choice. 
    I got better climb and cruise with a prop pitched about 2 inches more than a McCauley prop.  The difference was small about 4 mph but noticeable.  I did all this work and then updated to a  LYC 032 engine in the Swift with a controllable prop.
