Steve Stricker, this year's presidents cup captain has a simple and repeatable swing. His swing is a "text book" from many 3D graphs. He has great sequencing, he maintains a very stable upper body position, and he uses his body for power while delaying his wrist movements. 

If you struggle with more of a cast pattern, then study his wrist timing and practice training the body to control your transition.

It is worth noting, while Steve's cast pattern is great for accuracy and wedge play, it is not ideal for driver distance. For driver distance, you'll need more of a downswing load than a downswing cast.
