Swing 5.2: Left arm attached to body

Made some major progress.  Worked with a friend at the course.  Really helped with the chicken wings saying that I should really feel like keeping my arms together and swinging as if they are one.  Really conserve the triangle.  I also realized that hands were very far away from my body at impact.  So trying to work on that.  Finally and I don't know how it started but tried to really just not fire my left shoulder till very late.  I think this is helping because my lag is getting better.  It's what Ben Hogan said to do which is just turn the hips first.  I thought I was doing that but infact I was firing the left shoulder and starting my arms way too soon.  All this happens unconscientiously so had to reall concentrate on not doing it.  Anyway keeping my arms straight and as one really helped out my swing and now it looks much more beautiful and not embarassing.  I think I'm really on to something here and might finally have solved the chicken wing problem.
