Chuck, the Jensen Ugly stick did have a 1/4" sq stock LE at a 45. The two LE examples shown will fly no different, there just isn't that much of a change. The only reason I have ever sharpened a LE is to promote better snap/stall characteristics on aerobatic models. My pylon aitplanes have a good radius because good turning characteristics are more important then that additional 1/2 MPH.
