Although the system is meant to improve your draw, in fact it has improved other areas of my game e.g. my setup and accuracy. I am now consistently hitting the ball cleanly and going in the direction I want it to. I think these are the benefits of the various drills and exercises you suggested.
The "Draw" System has narrowed the exercise and search for improving my game because everything is presented in a neat package without having to search all of them individually.
Being new to the game I did wonder why certain drills and exercises were recommended. In the end I did find out they were great. The instructions are explained very simply and easy to follow but as I said I did wonder initially what they had to do with trying to draw the ball. The answers came in the end.
I used to slice the ball badly before but now I can hit it straight or if it goes right it is not as bad as before, at least it still stays on the fairway. It is a great feeling to see that ball stay on the fairway."
"This system has given me a better understanding of the mechanics of the swing which I could not get through lessons. After completing this system my drives are much straighter, but the biggest benefit has been with my fairway woods.
This system is a ready reference for anytime I want to refresh the mechanics of my swing. I have seen similar instructions in other books etc. but never laid out in the same detailed way as your system.
This "Draw" System has given me more enjoyment because I finally feel I can work the ball either way now. I'm on a 10.5 hcp and The "Draw" System is what I need to help me get down to a single figure handicap."
