Ben - as mentioned by Thomas, above, one of the problems with your prescription, and one of the major difficulties with playing the running game on modern courses, is the tendency to find approaches that have been heavily watered, or are grassed with something that's a bit 'sticky' and grabs the ball, like kikuyu, or paspalum that's not cut very short and tight. Then you're really screwed, you can't run the ball onto the green because it won't run on the approach, and so you have to fly it in.
