I HAD to post this. Rob Strano's GC video on how to use the "Carlton Dance" to play better bunker shots is just too good to miss!
Soft arms. Very soft arms. Soft enough that you let your elbows bend as you take the club back and then again as you swing through. Why is this good advice?
Because you want a steep swing that flattens out quickly at the bottom so the bounce on your sand wedge can glide through the sand. That's exactly what the super-soft arm action of the "Carlton Dance" allows you to do, almost without any conscious thought.
Some tips are just too cool to ignore. This is one of them.
