Trying to hold a flat left wrist is great for a hang back flipping beginner. Hopefully they get a better pivot and use the ground better and do not have to do that anymore. IOW, they get better at golf. The flat left wrist was simply an alignment to control the club face in Tgm speak. The club doesn't want to do that and any hindrance of the club acting like a club decreases accuracy and speed.
IMO, this why people can really struggle when they take Tgm or S&T to the wall. They end up with too much lean and too downward an angle of attack.
Trying to hold a flat left through the ball is good for absolutely no one. If it stays flat for some, fine. But trying to do it is never good. It's a free hinge, don't ever hold it. If you have to hold it or take a divot to hold it, you're doing something very wrong
