Any merit in learning 4 shots?
 

I want to train these 4 distances, because they are the most common yardages that I encounter.

1) 200 yd

2) 150 yd

3) 100 yd

4) 50 yd

how about you train a repeatable swing, then find use the club to hit these distances, much easier. Except for the 50 yarder all should be a full swing.
