I mentioned earlier on what I am working on. Here's another great Brian Manzella YouTube video on what I'm focusing on...keeping the zipper in front of the hands on the downswing.
Manzella also has another good video on "catching the drop." Supposedly there's a lot of critics of this method, but I think it's a wonderful thought to use. In particular, I let gravity do the work when I am putting. I am a good putter, but when I tend to have that little bit of a mishit, it's usually because I am not letting gravity do its job on the thru stroke.
