iacas,
Thanks for posting the video of Lynn Blake, basic motion, acquired motion etc.
I did get the PBS, but it's been cold and wet here so I haven't been out to the range and this post isn't about the PBS as much as it is about the fundamentals shown in that video.
When I'm hitting it poorly, the fault is always casting the club with a little over the top move. Made a last minute decision to get out for a round Saturday as the weather was supposed to be decent. I showed up as a walk on and it was going to be about an hour and a half before they could get me out. I took to the range with this video in mind and worked on the basic motion and acquired motion through a large bucket. When moving to the acquired motion I found that another fault was not taking the club back in one piece with my torso and that caused pulled shots. Taking it back in one piece got the club coming though from the inside at impact.
Got another bucket and tried to transition to a full swing. Most of the time it broke down, but I REALLY know what to work on now. During my round I took the "feeling" I had at the range. I wasn't trying to score so much as hit the solid shot. For the most part I took an extra club or two and hit 3/4 shots with my irons throughout the round. Some shots where I got it all correct, the ball was flighted so much better than any full shot I've made in a long time, On occasion the 3/4 shot was hit longer than a full swing for a given club. While I didn't concentrate so much on feeling lag pressure, I did concentrate on a one piece take away, flat left wrist towards the target and hands ahead of the club head at impact. I was striking it so much better that the grooves were scuffing the cover of the ball, and it's been a while since I did that.
I truly believe that I have found the blueprint for curing a lot that ails my swing through your posting of these videos.
THANKS!
