Split hand drill has made a huge difference to me and my open face woes which includes both slices and out to in shanks. I was so focused on trying to get shaft lean at impact I was holding off the release and wasn’t finishing the swing with any follow through.
From what I understand Shaft lean is an effect, not a thing. You can't do shaft lean as a position, it occurs because all the other stuff is working. On Youtube look up Mike Malaska, for me he has the most common sense approach to the swing of anyone I have seen. He's got oodles of vids covering all kinds of stuff.
