What do you guys think of this? It's the swing taught by Gary Edwin and used by Paul Casey, I believe.
The distinguishing feature of this swing style seems to be that you keep your weight on your front foot throughout the swing, and hence, never have to shift it forward as much in your downswing.
Here's a quote from this thread that sums some of it up:
"I am begining to understand where your theories have come from now, and it is one of the main differences between left and right sided swing. You think by holding on he has held the clubface open, thus verticle shaft (although its not verticle) through after impact. This is because you are used to seing the club go ''down and out'' with the flapping of the wrists etc . With a big stupid high right side follow through.
With Lambs swing he has stayed on his left side. And not moved back. He now does not have to get forward, so from here he can just bring the club back to where he started, notice how much more on top of the ball he is compared to most players. He can just turn through it. See most players have to hang back, because they get back and clear then hang back and it gives them this look of club going away from the target. Head down, extended arms through follow through then really around high right side follow through.
None of these fixes, are needed in Lamb's swing. you see his follow through and it looks like he has collapsed it at the top. But he has just folded it up. He struck it with a square clubface, and kept it square then folded it up. He does not need to throw it out right, because it is not closing how most people are taught."
Seems like an interesting premise to me. I want to try that on the range tomorrow...
