You look a lot more stable at the end of the swing in the top video which is cool, though I still think the flared feet would be helpful. Perhaps later.
Like someone mentioned earlier your backswing is very, very fast which isn't necessary and makes it hard to tell what you're doing with your hands. I think the reason you have no lag with the club is because you aren't utilizing your wrists. At address your wrists are tilted forward, towards the head of the club, and your arms and club form roughly a long straight line, right? I have a feeling this isn't changing much at all during your swing. When you take your backswing they need to hinge back the opposite way (towards your right shoulder) so that your arms and club form the letter L instead. Be sure not to lose your flat left wrist when you do this. This should get the clubhead behind your wrists and create the lag you're looking for on the downswing.
Check out this video, this is one of my favorites and watch it from time to time to remind myself how to do the backswing:
Edit: Here is the follow-up video about the downswing, also very good:
Wow, how did I not see this response?
Thanks for the help. I feel like my swing has greatly improved since I first started posting here a few weeks ago.
I also took a few practice swings at home and feel like a lot of the advice that is in these videos I've incorporated somewhat into my new swing. Unfortunately I haven't been able to get to the range this week to try it the swing so all I do is go and do swings in my yard. I videotaped a few and at least with the face on view, I was able to see my hands being in front of the imaginary ball at impact and a pretty straight front arm.
I'm playing tomorrow afternoon with a buddy of mine and hopefully I'll do well with the swing.
