Agreed, Sean. I'll shoot some swings while hitting a ball in the near future. I used this swing to hit my irons on the course the other day, and hit some beauties (and some uglies). I've always casted in the past, with or without a ball, so this is a step in the right direction. A flat shoulder turn encouraged that apparently. I made my left shoulder go under my chin and everything kinda fell into place after that. That is the longest I ever maintained the wrist angle on the downswing, and my follow-through and balance improved, too.
I'm retired, so I have the time. The weather here in Mobile has been beautiful recently. 60s and clear.
