Yes... for a Steep, Bent Plane, Early Releasing, Throwaway Type Slicer... the Trevino Fade would probably not be the best place to start. This guy needs to get on Plane, learn to control the Clubface, learn some basic Hinge Action, and learn to sustain the line of compression(Lag). Basic Imperatives and Essentials will help him.
For the good player, that is looking for a shot that will hold up under extreme pressure... the Trevino Fade, or "Block" may be something to try.
Trevino knew that ball was not going LEFT, and could just fire it out there in U.S. Opens... usually right down the middle! The FADES, by the way, that I have seen him hit, did not fade much.
