It was an article that discussed how the wrists were set (left wrist flat, right bent, like you do with the twistaway) at the transistion between the backswing and downswing. The article showed several pictures of David Toms.
I have thought about this article several times when BM is referring to his coaching of D. Toms.
Getting to a twistaway position at the top seem to be a good way to go, but I would not suggest experiencing too much with this without supervision of someone who know what they are doing. But I guess if one has a grip which does not allow for cocking of the right wrist, and monitors PP#3 (PP#3 behind the shaft at all times), it could be a good way to go. Note that I am a novice but this is my two cent worth...
