I’ve been working on stroke, trying to scratch in the same pocket as OB, CB set up three diamonds from OB, OB two diamonds from corner pocket, straight in shot. I can scratch now maybe every five-seven shots, and where I don’t scratch, I’m much closer than when I started. Checking that cue goes over the extra target donut to verify I’m cueing straight.
Every so often my elbow comes out a little, though less than before I started this drill.
Also, via video, and I can’t believe I was doing this, I found I was jumping up as I finished my stroke! I had no idea I was doing that. Still working on it all……
Sounds like you're on the right track. Keep it up!
