All other things being equal, will increasing ones lag open the clubface at impact?
After seeing my swing on vid a few months ago, I was appalled at how I lost virtually all lag at impact (my right arm and right wrist were fully straightened). Since then, I've worked into a net to try to improve in this area.
My goal #1 was to try to get my right elbow to feel like it is leading the hands into the hitting area. Goal #2 was to maintain my right wrist cock into the hit with a flat left wrist (I've found that Goal #1 really helps to achieve Goal #2).
Anyway, it was 60+ degrees in Indiana today, so I played a few holes. Early on, it was really ugly. Everything I hit was a slice. Before I started trying to make these changes, my normal ballflight was a slight draw.
After a few holes of this, I strengthened my grip. For many years, I've used a very weak grip (think Hogan's 5 Lessons...). I only played a few holes with a stronger grip, but it made my ball flight much, much better.
In thinking about it tonight and doing some slo mo swings with the mirror, a stronger grip or a supination of the left wrist were the only 2 things that seemed to square the face.
Also, is it a bad thing to us a stronger grip to square the clubface as opposed to better "educating" my hands for a change like this?
