I do not feel that the practice rounds WGT offers are true practice rounds. First of all there is no practice round for Tournament Green, Why?
I feel that there should be courses that are set up just to practice certain techniques, such as putting, Chipping, flopping, etc...
To practice these you have to play the complete round. I for one do not need practice on driving, but rather on other techniques.
I also notice that on the practice rounds, the distance you hit the ball is much greater then the stroke rounds, (non practice). And this is using the same clubs.
