As I discussed in my 'The Stack and Tilt Swing' book review, one of the beauties of the S&T method is that you don't have to use all of the components of the swing in order for it to be helpful for you to use.
One of the things I've worked on was keeping the weight more towards my left foot throughout the swing. One thing I have noticed is that before I even tried this is I hit very good shots from downhill lies. I also noticed on the range one day that I was hitting my punch shots further than my full swings. I believed this was due to being able to get the weight on the front foot at impact.
I added a little more waist bend at address and tried to feel the weight on my left heel. The impact alignments look good here.
I plan on getting more of a S&T-ish lower body action as well as working on squaring up the clubface at the top of the swing (very shut at the top right now).
