I don't know the instructor's name who is giving the golf videos, but his instruction is awesome. Maybe I feel this way because his instruction is exactly what I need for the level I am playing at.
For a very advanced player this instruction may be mundane. I would like to be at that level. I now understand the golf swing enough to know that really knowing being capable of making fine adjustments in various parts of the golf swing (grip, posture, stance, etc.) can make the difference between you playing a golf course and a golf course playing you.
If I only had another lifetime to figure it out, maybe I could master this game. As it is now, I will take the time I have left to continue applying and experimenting.
What a great and infinite game it is!!
